vaporiized is the only dude I've dealt with so far, but I'm willing to do half and half and if you add me on skype I'll show you my ebay that I Sold keys on, 100% positive feedback with 69 different people.
I have a bunch of US Black Ops 2 (II) Keys for Steam, and I'm selling them at $20 each. If you're interested, post or PM me.
