Heart rate monitor help

I'm almost to my original weight goal (would like to get down another 10 maybe, unless I can just slim down with exercise.)  I really want to start focusing on exercising, getting stronger, more toned, etc. I haven't been exercising really at all the last few months and am ready to get back in to it.

Can someone please suggest a wrist heart rate monitor?  I don't want one that requires a chest strap.

Thanks!

Polar and bowflex are pretty good...

My husband brought me the polar with the chest strap for Christmas and it the best Christmas gift EVER.  I love it!!!!  I work out any where from 6 to 7 days a week and it has truly elevated my workout.  I credit it for breaking my plateau and losing and gaining the same 5 lbs to it.  I have lost 7 lbs since Christmas and believe it was due to the heart rate monitor because I can see how hard I work out. I truly recommend it.

 I have a Garmin Forerunner 305.  It's red and black.  It is the Taj Mahal of running devices!!  I used it for every race I ever ran, and that's A LOT.   It's extremely accurate for monitoring heart rate (it does have a chest strap) and the GPS works in very remote areas, which is key for trail running.  You can also program it to stay within a heart rate limit for training purposes to make sure you aren't straining yourself or not challenging yourself enough.  I HIGHLY recommend it.  

I just saw something today called the, "Heart Rate Ring" in the Brookstone catalog.  It's a small device you wear around your finger--no chest strap required.  It says it's very accurate.  I think it was appoximately $30.  Check out the Brookstone web site--people usually review their products before they buy them.  Good luck!
