Done with 90 Day Body Revolution...what next?

I've done the Jillian Michaels Body Revolution twice now, and have loved it. I'd love some suggestions for a next step.

I like something that has a 6 days a week plan an an incremental increase in difficulty. I don't have real weights and don't plan to purchase them any time soon, so I need something I can do with dumb bells and a resistance band.

Any ideas? I'm open to more JIllian stuff or to something new. Thanks!
