Hello educated crowd. I need some advice. I'm going to buy my second round of Cathe's videos and again I'm going to buy in bulk LOL! so I can get my quantity discounts. The problem is that I decided to get CTX and now I can't get both Step Works and Power Max...I have to choose one. Which one should I get? I have an old summer 2000 Collage catalog and I read the reviews on both. I also saw the previews here, but I can't make up my mind :-rollen. Please help me choose!
