Op is back. Coinbase is clearly the winner for a noob like me. I signed up on 1/4/2014 (Saturday) and I was fully verified (bank account, credit cards, etc.) by Tuesday 1/7/2014. I bought my first BTC this evening (0.05 BTC). I originally signed up at Mt. Gox on 11/29/2013 and after several emails to support, I was finally verified yesterday, 1/7/2014.
Mt. Gox took 39 days.
