Heart Rate Monitor Suggestions?

[kellib]

I'm considering purchasing a heart rate monitor. I'm looking for a very basic HRM - doesn't have to have any bells and whistles - just good solid HR monitoring. Any suggestions?

I'd like to avoid the kind with the irreplaceable battery - if possible. I'd like to have something I can replace the battery in myself and continue to use!

Consumer reports rates the Polar F4 as the best value, and the F11 as the best heart rate monitor. My Timex has been going wacko, so I just broke down and bought the F4 (I don't need all the stuff on the F11 - although I do like the Chili Pepper color).
