Thats funny i found them right away using the link you gave.
I used CampBX for a little bit last summer. Stopped using them in favor of Bitfloor. But since Bitfloor is closing down, I have to find myself another exchange instead of MtGox. Was looking into CampBX again last night, as well as BitStamp and TradeHill. I think they are mostly trust worthy. A remember a couple of reputable forum users saying good things about them awhile back.
Thanks for chiming in.. Im signed up with bitstamp need to figure out a strategy for easy fiat withdrawal. I want to actively trade on two exchanges, sometime at the same time so im still looking for a bitfloor alternative.
