The Eagle mod lathe I got from SpeedTech RC is pretty good and handles all my comm cutting needs. It comes with a built in switch, can hold the motor for reverse or normal rotation, can use just about any cutting bit on the market(left or right side), has an ajustable guide plate to fit all armaratures and comes with a carbide bit. Its also a great price. It was under $70 I believe.
