I use a Polar RS400 and I love it. The chest strap will also transmit to cardio equipment, which you won't have if you're only wearing a watch. Polar also has a really good line for lifting like the FT80. I've got a buddy who has one of those and it's great for lifting. Kind of wish I had that one, but they're both really good. Overall I think Polars are worth the price tag.
