[edit:obsolete] BTC went up, 5830's disappeared

If you don't want to unload a new or used 5830, this post probably isn't for you.

I've been hacking around with my single 5830 for a few weeks, and want to press it farther than is either wise or advisable (I'm already at 1000 Mhz on air).

In the pursuit of that, I'd like to purchase any working full-length Radeon HD 5830 you might have lying about, in case I burn up my sole miner.

I'll probably use ClearCoin to create an Escrow Transaction, seems to be the thing to do for a noob with no rep like me.

If several people jump on this thread and reverse-auction, obviously I'd buy the cheapest card(s) I can find.  

Please state what model(s?) you have to offer, as I might be more interested in some than others based on my research.
