When I bought my bridgeport mill, part of the deal I made with my wife was that I would get rid of the mill I already had. The time came, and I managed to get it up out of the basement without any drama.
This mill is in great condition, I bought it new in January of 2000 from Grizzly. I've never crashed anything on it, nothing bad has ever happened on it or to it, and I didn't use it much. I had just started buying pulleys and belts and such to CNC it when I found my bridgeport CNC mill at a great price 7 miles from my house.
This isn't an ebay ad, but I hope other auction sites are also allowed in this category... Here it is:
