I am currently building a Quadcopter and need a flight controller that suits me. I am looking at the kk2.1.5 board. Is there any others that are good for around the same price? One more question, what is multiwii? Thanks!

The KK2.1.5 is an awesome board.
I spent all of today and yesterday rebuilding my tricopter with it.
I took off my APM 2.6 and put it on my glider.
I am much happier with the KK2 than the APM simply because of the LCD screen.
It is also 1/10th of the price of the APM.
I don't know much about multiwii.

KK board is an awesome board, if you don't use the stock firmware. 
The stock firmware has some bugs that you will experience sooner or later. It's better to use an alternative firmware like "Stevie's". But to upgrade the board you need a small programmer cable and an adapter to connect it to a PC.
You might want to check out the "flip 1.5" controller that seems to work nice with the FliteTest kits. The biggest difference is that to change settings you have to connect it to a PC, while the KK board has a display and buttons to change them on the fly. But the Flip seems to work nice without changes most of the time.
MultiWii is a software to control a multirotor RC model that can run on different hardware / flight controllers.
There is a special multirotor section on this forum where you can find a lot more information and help.

You'll get a lot of opinions on control boards. A lot of people on forum are guys who ENJOY building and tuning. For that reason it's my opinion that's why the kk2 board is fairly popular. My personal opinion on the board is it's a waste of time and money. For less money the flip1.5 or naze32 is a superior piece of equipment. After building a whole bunch of multirotors on kk boards, it's my biggest regret that I didn't switch to a multiwii board earlier. A lot is made of the fact that the kk board has a LCD screen which is a nice feature since you'll constantly be screwing with your settings to get it tuned half decent. With the flip and naze you'll need very minor adjustments to make it vastly more capable than the kk board. For the ok board you'll need to buy the board at about $30, then a cable to flash it for about $7, and eventually you'll need a LCD screen or two. Or you can get a flip board for $16 and a cable for $1
I think you're discounting all you learned with the kk2 to whip out a flip and say it's easy to tune . . . because if it isn't tuned out of the box, they're not.
I think a few quick tutorials for a reliable result (KK2) is better for them than a "plug-n-play" that's not. Yes, It usually is, but when it's not, it's a nightmare to step a beginner through the mess. Multiwii setup is MUCH harder to troubleshoot.
That being said . . . I agree, with the right tuning they can fly nicer than a kk2 ever could (although I've been very disappointed with the multiwii SL), but a beginner would never feel the difference.
yes . . . half the cost . . . nice . . . or $5 more and I can pick up RTFQ's clone of the kk2, pre-flashed with one of the better ROMs . . . but then again, I don't order from him anymore, really -- I've had HK international orders beat Paul's shipping. Nice guy and all, and good products, but for a guy who's got the natural in-country advantage, he pisses his advantage away.
Second board/build? Sure. Add on a GPS/mag/baro while you're at it! another hilltop to climb while you're already near the top!
First board? Good luck, because if it isn't right at first, there's a mountain you've got to climb, and no past experience to draw on.

Sorry Stepson I don't agree. That might be because I haven't had to troubleshoot my naze or flip boards. I've got a couple friends that started with the naze board on their own and didn't have any issues, but I do see a few people online struggle with setup. Generally those are the kind of people who aren't the best at following directions though and tend to get hung up on the tx setup more than anything.
Well . . . I have, and so you've seen others have too. Yes most of it is trouble setting up their radio (without having done it before it's not as trivial as it sounds, especially when working with a non-programmable radio), but the biggest places I've seen it are the non-traditional builds . . . which aren't so uncommon anymore.
V-tails (A-tails) and Deadcat's in particular have become commonplace and have trouble flying nice if the boom ratios aren't quite what the board expects. With a kk2 board (once it's flashed, which I'll grant you is not trivial) all the tools are in the user's hands on the field to sort those out.
I don't cringe telling someone to go to their mixer menu and reverse yaw in channel 3 and 4, or how to tweek individual settings . . . but for those running multiwii, I cringe a bit everytime I have to recommend "open your config.c and . . ." becasue I'm not sure they've made the leap to build their own ROM yet. From what I've seen Naze is a little better at this, but only a little.
Again, if it works right out of the box, fantastic, and 80-90% of the time, it will!
. . . but that 10% you've just signed them up for a steep learning curve with no warning, and no "starter board" to learn the concepts on first.
From how I see it, the beginner needs a chance to see above the treeline to learn. I prefer recommending they climb the short hill first -- Then they have both the view and an idea what the steeper climbs are like -- instead of recommending they approach the taller hill, and maybe the chairlift is working . . . maybe not . . . but even if it is, they're stil missing what they'd learn on the shorter climb.
maybe slightly more expensive, but I disagree that it's not worth it, and you got nothing out of the short climb yourself.

I see where your coming from Stepson. I just don't feel like the climb is much higher higher is all. I would concur that the odd builds will change the path up the hill though. I prefer the easiest path to the best view. For me that's been the flip and naze. The kk board has been like a very long downhill hike to a empty creek. Not hard, not tiring, just boring with very little reward and then I still need to turn around and hike back up the hill to get to that perfect view.
