My wife uses a Polar RS200. I use a Polar
strap at the gym and a Timex outdoors. The only thing the
Suunto has over the RS200 is the "
training effect," which you should get if you're following a good periodization schedule anyway. You never let a watch tell you how fit you are, you TT once a month or race.
I keep waffling on getting a
Suunto T4. I was all ready to hit the buy button when I read that the face is plastic.
