Mrd. D Holland: Here's a link to a fitness store that sells the part: http://www.fitnessrepairparts.com/cart/ViewItem/13001585

The heart monitor kit costs about $48 and about 55 total to have it shipped and it clips to your earlobe while clcling to display your heart rate. I sell a watch that looks just like a Timex Triathlon that has a large display timer and all you have to do is press a button to display your heartbeat. Many people are going to the watch monitors so they can be out walking, jogging, cycling, etc and check their heart rate at any point. If you're interested, I can ship you a brand new timer/heart rate monitor for $38, and can send pics if you want. [email protected]
