save a small fortune and build a sweet one yourself! Really easy build if you can weld and do proper fitup. You can find the motor for $100 or less on ebay. Imma build one myself as soon as I gots some fundage. Its pathetic that I cant afford to build this right this minute as cheap as it would cost. Really, this build would be under $200, take a morning to build. The diamond wheel costs more than it would to make the machine. I can't wait. Finally found a use for them old tires laying in the yard that came off a truck I don't have anymore, heh. Shit, man, sometimes you strike gold whilst surfing the interwebs.

I hope some of you put this to good use, I know I will:
