Here are a few of the really nice ones.
Just a note. If you cannot use redial by just pressing the talk or hardkey. Then odds are you will not be able to dial 911. Also most dont have smartdial.
This one looks like it has smartdial. Probably can use 911 and redial. Not sure though.

This one is super clean. No redial or smartdial though. Prob no 911 either. I use it and just have a police station in contacts instead of 911. In case of an emergency. Yah know.
