My lovely finacee wants a HRM, and I've been researching them. Currently Nashbar has the Polar M32 for $90, and a Polar F6 bundled with a Nashbar wireless bike computer for $109. Obviously I'm leaning toward the latter .
Anyway, I can't find enough difference between the two to make a good decision. I want to get what is best for her, she likes to treadmill and do group workouts at the Y, so I'm going for the "bang for the buck" here.
