If its not out of your budget then, since you want variety, I would highly recommend the CTX DVD. This DVD has 6 different workouts of all kinds on it - all the same format: 30 min cardio workout (huge variety here from kickboxing to hi/lo to step) + 1 upper body part. One of the workouts is a legs only workout, and the upper body parts can be put together (I think there is a mix on the DVD) for a total upper body workout). So there are so many combinations and varieties you can do just from one DVD.
I'm sure there will be other suggestions as well, but if you are just getting going, its an excellent choice.
The only drawback to it is that some of the step cardio is a little more advanced in choreography. I don't know if you've done any step tapes before, so it might take some work to get all the moves. Some people start with some of the easier step tapes to learn the moves first.
But there are certainly lots of options on there and it leaves you lots of room to grow!
