best device to tell me how many calories burned?

I am looking into buying something that will tell me how many calories I am burning.
Should I get a Polar HRM? Jawbone UP? Fitbit?
What do you use and how do you like it :)

    I've been using the BodyMedia Fit LINK armband since last Friday and absolutely LOVE it.
