Fitness/Calorie tracker suggestions?

So I've heard of the fitbit, but I know that is expensive. I tried getting a fitbit wannabe from Wal-Mart for about $30. When I used it though, it was not accurate at all. I did 2 FB workouts, each being about 35-40 mins long and one was a HIIT video. The watch said I only burned 80 calories from both videos. I immediately returned the watch lol. My question is, does anyone know some watches that accurately count calories burned? Any links and suggestions would be appreciated. :)
