I use Navy Federal Credit Union. You have to be a military/DoD civilian at one time, though - I can't remember if you were in the service/work for the government.
They've got great online, 24/7 SUPER polite customer service, and their branches are open late on weekdays and until 1 or 2 on Saturdays, depending on the branch.
I've got all of my loans through them, for good reason. They've always beat any other offers on loans - the last one I got, for a new motorcycle, they beat Ducati financing by 5% - 5%!!
My favorite part is that their 24/7 customer service is real people - you can call in the middle of the night and bank, apply for loans, etc etc etc. For those of us with weird work hours, or just have kids, that's a God-send.
Drawbacks: They generally have more branches around Navy/Marine Corps bases and hubs, but they're in expanding.

Navy FCU has been good to our family over the years. They seem to own the 'liens' on everything I own! Its nice to make one stop bill paying!
