Need Advice on HRM w/distance tracking

Options
I know I've seen posts related to this topic before, but my husband and I are looking to buy HRM's soon and aren't sure which way to go. Our wishlist is simple, we want one that can track distance for our runs and one that monitors heart rate continuously and calculates calories burned based on that so that we can get a better idea for all of our workouts, including running.

Obviously the Garmin has these features, but I'm wondering if we can get the same features for less with another HRM?

Suggestions???

thanks!
