I've never used Sunto, but I've heard nothing but good things about them. In fact, it's probably going to be my nexy fitness tracker.
I'm using a Garmin right now, which I've had no issues with whatsoever - I'd highly recommend them in fact.
I think it depends on what you want out of a tracker - you don't HAVE to break the bank if all you want is heart rate, pedometer etc. If you want something all singing, all dancing then you'll obviously pay more - if you're just doing basic cario and weights though, is there any point? I'd say probably not myself, but I get why people like fancy gadgets!
