| I am glad someone mentioned heart rate monitors.  How accurate is the Polar M61?  Most importantly, how much did it set you back?  I have looked and the lowest cost Polar was about $100.  I was skeptical of purchasing it because I was not sure how accurate it would be.  Does it do anything other than show your heart rate?
