Good idea - I just posted over on Ask Cathe. I was trying out here first, in case this has already been covered and I just couldn't find it with a search.
I do have KPC, and I LOVE it. I've got nearly all of Cathe's older step videos, and love them - miss them, now that it's tough for me to do hard core step in my workout room. I now use MIC (hi/lo part), KPC, and other kickboxing tapes that I have, but am always on the lookout for other non-step aerobics (I'm a runner primarily for cardio, but am "grounded" for the winter - weird lung issue this year with the cold air).
Anyway, hopefully I'll soon snag BootCamp and KickMax, and DrillMax when it's released!
