Heart Rate Monitor?

[aricbcool]

I'm looking for some recommendations on a heart rate monitor. I am starting a running program based on Stu Mittleman's book: Slow Burn. I'll be running for time/heart-rate, rather than distance.

My current criteria:

- Clock or Chronometer
- Heart Rate Monitor
- Durability

I've looked at HRMs online and the various features many have are a bit overwhelming. That said, if there's a feature you've found particularly useful, or just can't live without, please let me know.

Any and all recommendations are welcome. I look forward to hearing from everyone.

Regards,
Aric
