Less Gox = bullish for bitcoin!
I too use CampBX (mainly, and 2 others.)
I am pleased with their wealth of funding and withdrawal options. You can deposit with dwolla, but you can also send a USPS money order (no KYC necessary) or send a personal check (funds held 3 days, requires KYC.) Pretty dope.
I am not impressed with their user interface - I came from Bitfloor and the UI there was great. CampBX I need 2 complete page loads for every trade, and 25% of the time it glitches and sends me back to the home screen. But, as I don't do much daytrading, it works fine for my needs. I should probably just bite the bullet and figure out how to hook up a trading interface with their API.
The low volume doesn't matter for me because I'm not routinely trading thousands of $$$ of bitcoins. It does mean I don't have quite the opportunity on certain price swings, since Camp tends to lag behind with a dampening effect, but I'm willing to work with that for the pleasure of not using Gox at all.
