Sport Watch Help!

PixEm

So, I really want to start monitoring my heart rate, distance ran and calories burned, but honestly cannott afford a Garmin Forerunner Watch. Does anyone have a reliable, but non budget busting watch suggestions? I really want to know how many calories my workouts are burning because I never feel they are accurate. I also am not sure if I am looking for the right thing or not. Meaning do I look for a HRM watch or something else that will calculate calories burned. Any help is appreciated!
