That price seems a bit high. My brother's in-laws have a flea market, and had one of these. It was older that the one pictured on CL, it was a cool two-tone brown color with great graphics and text. It was a grocery store model that had the switch so when you placed the base of the bag on it, it'd grind. It would power up but the switch wasn't functioning, and they were asking $75. He also had an even older Hobart model that had the tin hopper - that model you could do coffee, wheat, and corn.
If I brought home either beast I'd be sleeping with the chickens (again ;-). This is one reason why, I need a coffee shop...
