i did over 1500 cans by hand. I finally set up a motor for it. Most will never need the motor. Its not that big of a necessity. The motor was $90 something from Grizzly, the belt $20, and the pulley I had made by a machine shop for $35. now its electric or manual. oh and $12 for the foot switch from Harbor Freight.
you can get motors from Craigslist for $20 all the time. They were all far from me though and easier just to buy a new one and have it shipped to my door.
