In general you would be better off with a HRM in determining relatively accurately the calories burned, and a middle range Polar (about $100) should get the job done well. I had another brand and was not really happy with it until I bought myself a Garmin 310xt, an old version Garmin that is now much more affordable. The new version costs as much as an Ipad. This Garmin that I have is suitable for outdoor triathlon type workouts, it is a great device, but if you are doing mostly indoor workouts, it would be an overkill. I have a few friends totally happy with mid-range Polars.
