You might be thinking of Doug Saito. Doug is a club member who holds live auctions, but who also does auctions by mail. You can subscribe to Chip Chat, which is what he calls his mail catalogs, by contacting him. I highly recommend his catalogs as a wonderful source of information as well as a source for some truly awesome chips!

I could be wrong, as I've never attended one, but I believe that he usually holds a live auction, in Las Vegas, the weekend before the convention...someone will correct me if I'm wrong.

Here's a link to the results of his last live auctions (he also accepts mail and phone bids at his live auctions), which has contact information. I'd definitely recommend getting in touch with him!
