I have a Nike Imara (I don't know if that's spelled right).
It's a regular watch that has the HR monitor to go along with it. I'm lazy and don't want to fiddle with 2 watches (i.e. putting on the wrist band along with my watch when I workout). I just put on the HR strap and go when I'm working out.
It does everything: AVG HR, you can set HR zones (low, target, high), calories burned, intervals, an alarm, etc.

It was about $100 and I've had it for a few years. I really like it.
