What are some of the best non smart phones for AT&T?

I'm on the ATT site trying to renew my contract. I can't afford a data plan and they said you can only get a smart phone if you have one. So what's the best non smart phone out right now. I know it depends but I have no idea where to start looking and don't know much about phones so if I could just get some suggestions. Price isn't really an option since I'm starting a new contract most of the phones are free a real cheap. Thanks
