I was going to ask how that went. I'm very glad that someone got use (and cash) out of it. Just too big for my situation.
Probably a good point. As someone else said, the kind of person bidding on machine tools probably won't screw you. Kind of like accepting a check from a total stranger, at a gun show. You just don't get screwed by that sort of person.
Seems reasonable. If you're just selling the sort of stuff I see you mention here, you're not as vulnerable as if you were selling, say, beanie babies.
Last bouncy check I was given was when I was 14 and had a paper route. I learned the "Sorry, you need to pay in advance" game pretty early.
