Pilates Suggestions?

I had a Pilates video I liked but now haven't done in forever.  I'm looking to join this century and get a DVD. I could just buy the same one but wanted to try something new.  Do any of you have one you love? Preferably not to tough, I'm basically starting over and it would also be great if it lasted about 15-20 minutes so I can have time to do other cardio stuff too.  Doesn't have to be Pilates, just something for core-strengthening. Any suggestions?
