Check out their checking accounts, not savings accounts. Look for things like "bonus" checking, "rewards" checking, checking "plus", etc. My savings account actually pays far less than my checking account at my credit union. Also, there are out of area credit unions that you may qualify to join, if there are none available in your area. Maybe some personal finance sites might have a list of high interest checking accounts. Be aware that there are usually strings to these accounts. For example, I have to have at least one direct deposit and ten atm transactions a month, otherwise my interest is not as high. That's never been a problem for me.
My credit union is only open to people in this area who work or have a family member who work in a certain career, so I can't help you out with a name. I bet with some more digging, though, you could come up with something. Good luck.
