Old Glory Bank has been good for me. They don't have much in the way of branches (I think their physical location is in Enid or El Reno), but that hasn't been of any concern for me.
They're not in Enid ... never heard of them.
BTW - I also have an account with Communication FCU, but Tinker is my first choice and gets the bulk of my business. No real complaints with CFCU, but I have found Tinker to be a better fit.
