from work I can get a discounted Fitbit device
I already have a zip but can get the following at these prices
Flex for $30
Charge for $50
Charge HR for $75
Surge for $150

I'm considering the either the Flex or Charge HR, but the Surge interests me because of the GPS, I didn't have mobile service today and could have really used a GPS. Though I've heard the Surge doesn't have a good GPS. Am I better off getting a separate Garmin for GPS and the Charge HR? I have a watch with HR, the kind with a chest strap which I never use because of the uncomfortable strap, so looking for another HR device.
