Key Bank's probably the best option since they have lower interest rates and better re-payment options. You're credit has to be pretty solid, though. I found this out about a month ago when I applied. Even with my mother as a co-signer I was declined. Turns out BOTH parties have to be credit worthy for the loan. To me, that kinda defeated the point of having a co-signer. Same data sent to Sallie Mae, and I have all the money to finish CMEL-MEI on account.
