A bike computer w/GPS is going to be much more $$ w/drastically less battery life. I'd suggest getting a basic computer that will have your Must Have & Important features. Regular odometer-style computer batteries last for months. I'm sour on GPS bike computers esp for touring, routing functions were/are poor. Phones are killing the GPS device market anyway. I'm replacing my bike computer too & going for altimeter this time which is a bit $$ extra but kinda fun to see if hills were as tall as legs reported?
