I have a sportline model that I bought at Walmart. A lot of people reccomed the Polar brand, but I couldn't afford it. I'm so glad I went with my Sportline though. It works AWESOME! I can see how many calories I burned, how long I was at my target heart rate for and it yells at me when my heart rate gets to low or to high while working out.
To check for accuracy, I wore it during my workout and then I went to several online workout calculators and put it what type of workout i did and how long I did it for. The numbers matched almost perfectly.
