What is the best fitness device for me.

MeganKG21

Im very interested in buying a fitness device of some kind to monitor my calories burned. i have a pedometer that i never wear through my health insurance but i want something more so that goes off of my heart rate.

I have 3 options im looking into,

-Fit Bit, Its the pedometer that is advertised through this site, and they have done a good job in marketing because i am interested.
-Bodybugg, its a well not really sure if its a HR monitor or if its a pedometer, its not really specified, i think this one is cool.
-Or any type of HR monitor.

They all have their pros and cons i like the fit bit because it tracks your sleep that my sleep pattern has always interested me, the body bugg because it goes on your arm and has cute frames.
So pretty much all of those are superficial reasons to purchase something over $100.

Looking for input as to which it best and how accurate they are.

Thanks in advance for any help!
