You are looking for galvomotors. They are basicly a high horse-power meter movement. Meridith Instruments in Phoenix sells used ones for about $75 each. ( quite cheap compared to new ones ). Email me if you need the address. They also have a lot of neat used laser stuff. John ..................................................................... Have fun, Play nice, Don't fight.
