gbabb:I see on this string, most everyone praises the F11. I just ordered the Suunto T3 on ebay after reading tons of reviews from all over the web. Seemed like a better monitor than the F11. It hasn't come yet (hope to get it this week) - but am curious to why everyone here seems to like the F11.
There isn't much that differs overall, don't underestimate the force of commercial 
It doesn't matter that much if it is a Suunto, Reebok, Polar or habla-habla as long as it does the job and give you a somewhat reliable result to review. It's still just a tool to see the borders of our training a little more exact, but it's still unsharp in the edges. The person who lives entierly by his/her HRM have missed the purpose IMO. 
I'm not afraid to make my next HRM a Suunto. Suunto also do dive computers/watches, and if it wasn't for a minor "out of stock"-problem my dive computer would have been a Suunto, so I had to go for a Uwatec Aladin Prime. The same goes for dive computers/watches - Most brands/models does the job so then it's just a matter of shape and color ;)
I think all of us using HRM's are quite satisfied with the particular brand/model we use and that's the main thing. 
When everything is said and done; you can say it's easier said than done! :-D
