Doug, maybe your reputation is well known, you and when they seen it was you, the price went up. Maybe you should come in disquise!
I agree with Firelion too, some people think they have priceless antiques and its really just junk, but they heard about a similar thing that sold on ebay and they think they have the same thing. Some people dont have a clue. Ive seen people ask $50 for a stove that isnt worth $5, and then theres the good things like TLC's 502 or my 425 for $10. You never know until you get there. I guess thats what keeps me going to them is the thrill of the hunt. When i score something nice, it makes my day!
