Anyone here use or can recomend a decent pedometer ?

My Dad who is 77 is still in great shape and enjoys his walks everyday , besides still working full time just because he enjoys that , too.

He has his walk estimated at about three miles but I know he'd get a charge out of actually seeing how far he's really walking.

I'm sure there are pieces of crap out there I want to avoid buying so wondering if any of you could make a suggestion for a good one ?

Thanks for any info you can provide ...
