I found a used but great condition wilton 2" belt grinder for 300$ with extra belts. Its the 2500$ model. Is this a good deal? Better than that, should I go for it once i can rack up some money?
$300 would be a good deal even if you had to replace the motor. Andrew's right; it won't last long and don't expect to see it repeated. Sort of like when a buddy of mine ran into a woman who was selling about $1000 of camera equiptment (40 years ago) and the lady flatly refused to take more than the $150 that she was asking for it.
