My mom uses LGE and I use IBM. Both are easy to join. We have received excellent service at both. For S. Paulding, you would have better access to LGE (there on 278 on the left just before you cross the county line). Seriously - both of them have given EXCELLENT service to us, and each of us has been a member for over 20 years.
I hate banks. If I had to use a bank, it'd be BB&T. They didn't take bailout funds, and they are some pretty straight-up folks from what I hear. I think I've also heard halfway decent things about Fifth Third Bank, but I'd have to check more on that one.
