I need a Heart Rate Monitor

I have the Polar FT7. It was about $100 if I remember correctly. I love it since it has a chest strap. I debated a lot about what I wanted to get and saw that the chest strap helps you get accurate reading. I also like the FT7 because it is one of the cheaper ones that still had really good reviews. The calories burned seem quite reasonable. just be sure to update your User information, namely weight, as you lose it. It does make a difference on number of calories burned. Not a huge differnce, but enough of one to count over time.
