I bought it since it was so cheap, and anything seems an upgrade from the borrowed Ryobi I've been using, which has now also stripped, so my blade stays up. Here's the verdict. I'm no expert on finer table saws tho:
Original owner's manuals for both the saw and unifence were available.
Owner admitted to doing absolutely zero maint ever, and also claimed only occasional DIY hobby use... Several pieces of furniture, exterior millwork, etc.
The motor and all that appear to be in great shape. All paint in great condition. Absolutely zero rust on most of the unit, including the metal "cabinet", except for minimal surface rust on the trunnion? and similar bare metal parts (benefit of a CO climate I spose). Moving parts definitely need cleaned and lubed, if lube is SOP specified. Supposedly the belt is original , but doesn't have any fraying, cracking, or other excessive or irregular wear. It ran nice and quiet. There was zero blade wobble or motor play cutting or pushing and turning with hand.
It has a WWII 40 tooth TK blade in it, put on when bought. It's never been resharpened, is pretty dirty, has a few chips, and needs some TLC, but to my eyes looks useable, except for the chips. It cuts ok, although in retrospect, I should've tried harder to find some scrap oak or hickory maybe to test with, not the SYP 2x4. Hopefully is salvageable for a reasonable price, but if not, I guess I've got one heckuva utility blade. Anyone care to speculate on costs I might be looking at? I'm gonna be ashamed taking such a neglected blade in for reconditioning.
The Unifence extension table has some considerable wear from being moved too much, and too carelessly, apparently. There's a big chunk missing where the center bracket underneath ripped off. The laminate is peeling along the edges, and the brackets appear a little bent. The top surface is still pretty decently smooth I spose. Not sure what the owner cut with this thing over its lifetime, but there are a few deeper than fine, parallel sliding scratches/gouges on it and the cast iron table top.
Besides the left wing needing alignment, the cast iron tabletop seems in useable shape. The sliding scratches bug me, and depending where, I can see less than 1/64" of light beneath a straight edge in front of the blade.
The Unifence seems in good shape aside from some wear and tear from the moving around. It also appears whatever the heck the sharp objects (screws?) were got ahold of it a few times.
It also came with the factory throat plate, and two aftermarket zero clearance masonite? plates (one for dado and one for regular blade). The original SideKick blade was also available in used condition.
At this point I look forward to restoring and using my find. Will see how things pan out. Any suggestions and hints are appreciated. ...time to start making progress
