I almost forgot. There's a new exchange being created in the US by the dev of P$, AMK, and GOD. He and some other people are putting it together because they are sick of all the bullshit exchanges out there. I can't remember what it will be called, but I'll look it up. I can ask them when they get it up. Also, Atomic Trade seems to be another possibility, as they are quite reputable, albeit smaller.
