My favorite vendor is www.headsuphobby.com out of Central Florida. I placed an order at 9:30 pm, last night. Woke up this morning around 8:30 am and already had an email stating my order has shipped! They are the BEST online vendor, IMHO.
I will second that! While I live in WA state and the shipping time itself is long (no way around that and certainly not the fault of Headsup) I got the "shipped" email early the next day. All the merchandise worked great and I'd certainly order from them again.
I've had one order from them and it too went smoothly. I've heard they have excellent customer service. Probably because they are so good up front its easy to make people happy when something does go wrong. Also, love hobbypartz. The Dynam ESCs are the same as Turnigy plush and I can use my Turnigy programming card on them as proof. They also are cheaper and ship from in the states. The Tacon motors they sell there are the best I've used and they do not break the bank either.
