I'm going to start unwinding some of my position and was wondering what services US folks use to sell their Bitcoins and get the funds transferred to their bank account? I've generally used Coinbase to buy my Bitcoins, but lately they've been "mysteriously" cancelling my purchases (when the price has gone up post purchase) and I'm really beginning to not trust them. I'm not claiming it's purposeful (though I've been a customer since day 1 and they know by now I'm far from high risk and have level 2 validation), but their customer service, which was great at the beginning when it was just a few guys and not a lot of customers, now is 100% useless (no one ever responds), so I'm really worried about them even touching my Bitcoins or my money.

Are there other US services that people use to cash out? Thanks!
