Since I've had an experience with Dan, I'll chip in. He had a DoAll saw blade cabinet for sale on craigslist for $200 about a year and a half ago. I have a DoAll 3612 and thought it would be nice to have a matching cabinet. I called him up and we scheduled to meet in a couple of hours. I showed up at his shop in the evening, around 6:30 or so. He showed me in and I was impressed with the amount of machinery he had; a fair amount of it was in very nice shape. We walked to the back of his shop and he showed me the cabinet. It wasn't mint by any means, but it was in decent shape. I agreed to buy it, gave him the cash and backed my truck up to the shop door. I noticed he was acting a little odd as we were loading it in but didn't think much of it, it was about 8:00 by this point and maybe it was late for him? Anyway, I drove home and let it sit until the next day after work. While I was unloading it, I realized why he was acting funny: the lower part of the back of the cabinet was rusted and bent. I can't prove it, but I was believe he was trying to conceal the damage as were loading it in, knowing full well how bad the back of the cabinet was (is). I decided to chalk it up to a lesson learned; you can't see the damage from the front.
I'll end with this: if he was willing to misrepresent a $200 cabinet, is it likely he will be forthright and completely honest about a $10,000 machine?
