Sneaker, 'sure hope you get some good replies. I think they're okay, but I'm sure gonna' say that conditionally, because of no personal experience.
I do know they have just about anything you can pay for though; that's the sad
thing though, it ain't really an auction like Ebay or wherever, the prices are pretty much fixed more or less at the going rate, and you bid on something, it's usually yours. I think sellers do have ratings though, so that may help you stick with legit people.
Good luck !!!
