Beware that some of the Polar units do not have user replaceable batteries in the chest strap. Or so I understand. Also, it appears to be important that the HRM has coded transmission (chest strap to watch). I assume any digital transmission meets that criteria (to protect against other HRMs, etc. interfering with your unit in use).
Someone please clarify this issue as I am also looking into HRMs.
I thought the Polar F11 had a user replaceable battery. But the sheet I picked up today at REI says it is not.
may be a good place to buy online, but I do not have experience with them.
Or you can get a combo cyclocomputer/HRM if you want to go that way, but it would seem to defeat the inexpensive part of the equation.
