Saw one Chi-Com went for $750. There were some good deals. At one time, I thought I wanted a Dan Wesson, but don't anymore.
I see doing a "search" covers all catalogs, so if you know something specific you can find out if it's in an upcoming auction. Right now "Wesson" pretty much covers it for me.
PROXIBID: is a very bad site. Bad. Bad. Very bad.
