HRM + Calorie Burner Watches

Libby81

Can anyone recommend a decent heart rate monitor that gives you calories burnt figures? I've been trailing the internet and the info is all so confusing. From what I've read the ones which you have to programme in your height, weight and age appear to be the ones that would provide a more accurate reading.

I really only want it for when I do my gym classes or just a gym session, and I don't really want to spend a lot until I see if it works :S
