I'll precede my comments with --
Is this an auction or an estate garage sale? Your description, here, seems to indicate a garage sale type venue.
--It's an auction held by a company, but will be held at the site of the shop. Upon my request, they let me view the TS early. If they are wise they should remove everything from the shop before the auction starts and move it out to the yard/driveway.
Your subsequent description still hasn't convinced me the saw is not worth $400, $500, $600. Sure, you can always do better, but when and at what greater cost (maybe)?
--I do not doubt that the saw is worth $400-500. My plan was to buy the Grizzly G0690 (~$1200), so I'm not getting sticker shock. If you happen to have read another thread I started, then you may know have been arranging the details of the
240v wiring now. I think that your assessment that someone might have gouged it with a skilsaw is right on. In fact. they (more than) scratched it up completely--probably using it as a workbench as you mentioned. BTW, in view of the confined work area of this shop, that makes the most sense. You are insightful, Sonny! Anyway, the tabletop is unsightful. Having a new tabletop on the saw would change my outlook on it. I still have time to look into that possibility. I do not anticipate that this option is viable but I'm considering it now.
At the same time, I don't doubt your ability to evaluate the tools, especially after an onsite inspection. --Don't give me too much credit, I'm a relative newbe buying my first and, most-likely, last TS. I removed the throat plate insert to see what kind of splitter, if any, might be present. There was piece of plastic perhaps
1" by 2", with a large vee on the end in there. The saw is a Delta Unisaw Platinum Edition. Can anyone describe how that mechanism "works"? This saw had a "dust bag" connected at the bottom (I presume a DC attached there may not be quite as effective as on some more modern saws).
--So for another $600 (twice the price), I could get a saw with a riving knife, having a top with a mirrror finish, probably better dust collection, simpler delivery to my house, and a warrantee. The Delta saw did sound great (I haven't heard a Grizzly). The Delta TS did not appear to have a fine adjustment mechanism on it's Beisemeyer fence (surely it's an older model ~15 years).
--Your post was helpful. As always, thank you for helping me think!!
