Joe, you have to check this out. NEW 5" HIGH TORQUE CNC TYPE ROTARY TABLE W/ 
DC MOTOR Item number: 3858692504


its going for 41.00 dollars, and I have been watching these, not one has 
sold for less than 30.00 and he has sold 2 per day for over a week.
Not bad for something you can buy at surplus center, plus he wants 10.00 
shipping.
