good credit union, is a great idea, but not all CUs are created equal. Do some sleuthing, see if it's licensed by the state or federal because that makes a difference what rules they play by. Like anything, Google it, and hear what the really pissed off people are pissed about.
I'm cautious about the ask friend's advice because if they have/had experience with a particular CU, and they are still with that CU, they'll probably give it an OK. If they haven't, it's just hearsay. But there might be something about the operation that doesn't bother them, but would drive you nuts.
For instance all the cashiers are chummy to the point of you can't get in and out in less than 15 minutes. That would drive me up a wall, miserable prick that I am.
