I wish you luck contacting the BladeForums management, but I don't think they'll get involved. I contacted them after they'd banned someone I'd just bought an INFIcoot from (and which I'd sent a money order for). The response I received was that if I experience a problem, I can post about it in the Good, Band and Ugly sub-forum, but that they don't have any authority to take action on individual sales.

When I received the INFIcoot with no problems, I wrote again to ask that they reconsider the ban against him; I said that he'd done well by me and passed along that he had been undergoing reconstructive surgery and taking pain meds, so I suggested that they give him some benefit of the doubt on the argument with a Mod that had gotten him banned. Their response was that he'd had his chances and that any extenuating circumstances were irrelevant.

Bottom line, I've had very good luck with the folks I've done business with on BladeForums (although for the most part, that's back when I could search the GBU for positive/negative comments about their prior transactions). However, I've gotten no traction when trying to deal with the BF management; perhaps you'll have better luck than I did.

As far as transactions go, I know that a lot of folks don't like doing business through PayPal, but I'll sometimes use them even when the seller passes along the fees because there's more recourse than with a money order. It's not fast or easy, but I have filed a dispute/claim with PayPal and gotten my money back on a bad eBay transaction.
