Thank you all for your opinions and input! I have actually been doing research for awhile, and based on that combined with your responses, I ordered a Polar FT7 today from Amazon. It was less than I expected ($90, shipping included!) so I am now anxiously awaiting my new toy *L*
I'm looking forward to being able to more accurately measure the number of calories I burn. I'm a bit of a geek when it comes to spreadsheets, so I foresee a chart in my future keeping track of the length, intensity, and calorie expenditure of every workout.
