+1. I have just started using CampBX and I expect they'll see a lot of my business. I have a couple minor nit picks I could bring up, but it's not really worth it.
There BTC prices are avg about .40 lower than the other exchange I wont name(and never use again after readin the horror stories around here)
I was wondering why the prices are so much lower?
Because it's easy and cheap to move money into and out of CampBX if you're based in the US, but harder/more expensive for everyone else, due to the particular options they have for moving money. This decreases demand.
Don't take that as authorative; there's probably more than that involved.
