Could be a tad high on the asking price.
I signed up on the site last month, as I had several guns to sell. And they were an interesting variety at reasonable prices, including a single digit serial number Colt - but I never got a single email query. Usually, the Colt is at least good for a few, "Wow, first day gun...", responses. So I don't know what kind of traffic they're generating. I wish they had an "Item Viewed" counter.
