Heart Rate Monitor... which to get?

Options
I recently borrowed my friend's Polar F11 heart rate monitor and after one workout I decided I needed to get one of these handy little things. I've started looking around and I was hoping for advice on brands and models, preferably from people with direct experience with the products.

A little background on me:
I work out on average 4-5 times a week, doing a bootcamp/circuit training type class. I feel my fitness level is very good, and that I am not a 'beginner'. I am not looking for a watch that has GPS or fancy assisted training programs to 'guide' me. I would like a simple, comfortable monitor that can tell me where I am in my zone and which zone I'm in (fat burning vs cardio etc). I like the idea of being able to trend my workout data over time, but this isn't necessary.

These are the two models I'm looking at and I was hoping for feedback:

1. Polar FT40

2. Suunto t3d
http://www.suunto.com/en/products/Heart-Rate-Monitors/suunto-t3d/suunto-t3d-black/


I have heard both good and bad things about both companies, but I was hoping for some feedback from you beautiful MFP people. Also, if you have other brands models you would recommend, please do!

Thank you!
