I may have posted this info in the past, but a reminder is always good when it comes to quality building tools. Fourmost Products makes some very useful tools, as shown below. I've had their Miter Saw and Miter Sander for a few years, and today I saw their Miter Cut at a swap meet and jumped on it. For $5.00 it's WAY below retail price, and other than being slightly discolored it was in great shape. It uses a standard razor blade and works as a chop-saw, perfect for cutting smaller sticks. These tools run somewhere around $25-30/each, and as people move away from balsa builds to the (b)ARFs they may make their way to swap meets more often, so keep your eyes open!
The Miter Saw is the most useful of the 3 tools (in my opinion), and it sees a lot of action on my balsa builds.
The Miter Sander isn't quite as useful (again just my opinion), but still sees it's share of action.
