Gadgets that calculate calorie burn

[honeybunch1]

Several of you have commented on doing Cathe workouts and what your calorie burn is - what sort of gadgets are you using to determine this? I love electronic gadgets, but am dubious about those that claim to calculate calories burned in the workout, such as those built into the computer panel of a treadmill or the like. Could someone recommend an ACCURATE calorie burn device for me?
Just Do It!

I think that most people who are commenting on calories burned are using HRMs for the information. Now, I know that my HRM calorie burn registers high, so I don't usually pay much attention to it, but I think the really good HRMs, like the Polar models, are fairly accurate as you have to enter a good amount of information into them to get the data back out. Perhaps someone with a Polar could elaborate on that?

I have the Polar F4, got it right before Xmas.. and Wildgirl is right, you enter a lot of things, height, age, weight, gender etc. I really like it, even if the calorie burned number is not exact, it gives me an idea which type of excercise, eg Low Max vs the treadmill are burning more or less calories.
