I have had a Wellsaw 58 for around 27 years now, it was my first "machine".
They are very commonly used by electrical & mechanical contractors so they may have had a lot of use. I'd say most of it is easy to repair or you can probably get parts from Wellsaw for it.
Mine came with damaged step pulleys and a piece broken out of the vise so it wouldn't clamp but I welded the vise back up, calculated a single speed for around 100sfm blade speed, purchased some Congress die cast sheaves at the local hardware store (can't do that any more, its property is converted into high end apartments...but you can buy them on the 'net)
I made my own table for it, easy to find a piece of 1/4" steel and carefully saw the installation kerf on top of the existing guide, then a couple of flathead cap screws, pack of shop towels to make a seat cushion and you are off!
You are only limited by the 7x12 work envelope...top is an S8 and bottom is an S10 I-beam.
