CSMC's integrity may not be up to snuff, when it comes to their auctions, if feedback is accurate. Read a couple pages of feedback to form your own opinion. I can dismiss one negative comment, but several with the same complaint makes me think twice before dealing with CSMC.

As I see in the second feedback, "penny auctions" are not always the best outcome for the seller.
