I love Electronic Goldmine, but... Surplus Center has them for $2.99 every day.

Are you going to use this for a FCG? One thing to consider re FCG. There is a lot of side load on the bearings. And keep in mind that the crank needs to be 1/2 the length of the intended travel you are looking for. So if you want your Ghost Head and Arms to move up and down 12 inches which is not that much, your crank must be 6 inches. So lets talk torque. 1 Ft Pound is the force of 1 pound at 1 foot. So if a motor puts out 10 Ft pounds, it can lift 10 pounds 1 ft away from it's center of rotation. The motor that many people use for the FCG is a motor from Monsterguts. It is an AC motor and puts out 50 Inch Pounds. That about 4 foot pounds. You should shoot for a motor with that kind of torque.
