Turbo Jam also mixes some kickboxing but it has a very big "dance club" atmosphere. You might be able to find some clips somewhere. This series seems to be hit and miss with people. I had the series in 2005 before switching to Cathe and I enjoyed them but I just naturally prefer gym style workouts.
Beachbody also has another instructor, Shaun T, who specializes in dance. His programs are Hip Hop Abs and the '80s-influenced Rockin' Body. From what I've read, these programs are easier than Turbo Jam--those are int./adv. but can be modified to low impact.
You might also be interested in bellydance which can mostly be done low impact. There are a lot of workouts around and some, like Rania's, can be found pretty inexpensively.
I hope this helps some.
