Yes, this guy came also along my way.
I bought the Fredrick Hymes III of him, when he had it for "buy it now" $450 on the bay. It's some months ago and I thought it would be a fair price, but then it turned out that he has lots of them.
But I don't think he's such a bad guy. Also I have to say, that I didn't buy anything else of him, because he always seems to get top prices.
Would be an interesting topic with the bad dealers. Start one, I'd like to hear your stories.
