Hi,
I know it's old, but I'd get Power Hour, Maximum intensity strength, and Body Max one. These are excellent workouts! You get some great weight training endurance and strenth, a short but intense cardio section, then a great cardio/leg circuit. Once you exhaust them as produced, you could mix and match and still keep it fresh for some time to come.
I think it's easier to do your own cardio, than your own weight training.
