If you look at videofitness.com, they have descriptions of most videos. You can look by instructor.

Kathy Smith is very good, but can be annoying. A lot of people like Tae Bo - they even have a Tae Bo Jr.

I've seen some videos advertised that are supposedly by the INSYNC type choreographer. They look fun, and I know my daughter likes that stuff. I think it's Darrin's Dance Grooves.
