What is a good pilates or exercise DVD out there?

I need some sweat! I only do walking right now, and need something more! Something simple and fun would be great, I already have the mat! I am thirty something and not overweight, but could stand to lose a pound or ten…inexpensive is a plus.

I love pilates! I download my workout videos from http://www.workoutsondemand.com . Not only are the videos really good, but supper cheap too! Here is the page to all their pilates workout videos: http://workoutsondemand.com/workouts_pilates_mat.htm
