WaMu is vaguely spotty and I've heard some awful things about them re: overdrafts and checks (a friend had problems where deposits were only processed up to 11PM but withdrawals were processed up to midnight, which was pure stupid.) We're with Wells-Fargo, which is ... well, frankly it's good as long as you don't have any actual money issues or problems with your account ever, but God help you if you run into any kind of financial trouble, because they'll skin you alive. Also be aware that they process withdrawals not chronologically, which is sane and normal, but from largest to smallest amount on a given date.
But they have this nifty direct deposit advance feature which is kind of handy.
