I'll add my name to the list of people of who have been happy with Coinbase.
I had to wait out the transaction times, but since there really aren't many options in the US, I'm not complaining.

Yes, their prices suck. Yes, if your a newb and want to signup and buy bitcoins RIGHT NOW, you're going to have to wait.

However, for me, they have been upfront about their policies, and have lived up to what they said they would do. YMMV
