My first band saw was a craftsman. I think the biggest concern was that guide blocks and things were difficult to find, as most everything in current use is sized to fit the standard 14" Delta and the knock-offs. I had the 12" Craftsman, so it had just two wheels, not the 3-4 you have. I have always wondered if these are harder to track or wander under a load.
I have the big Delta now as well as the look-alike Jet, love them both, but you don't just pick them up and move them around as they go 225# each. Something to be said for cast iron, not die-cast aluminum.
But........that is a low enough price as long as: 1. all bearings seem tight 2. the guide blocks and blade guide assemblies are there and in good condition 3. the rubber tires on the wheels are in very good condition. Trust me, you don't want to replace parts when you get it home, especially the tires.
Hope this helps.
