Basic Step (no BF) came with the Wal-Mart small step. The first time I tried it, I was ready to drop it from a high-rise. Later I got into VF and with everyone raving about her I decided to try again. I just did a little each afternoon until I got it. Before long I pre-ordered LIS and bought the Classics, HSC, and BS/BF.
That was last summer, and now they're all too easy! I traded them for more advanced w/o's (Low Max, KPC, Gym Styles) and I'm waiting patiently for Xmas to use my gift card.
I have to add that I'd been trying to teach step, but had trouble grasping anything but the basic moves. Cathe's DVDs taught me the complex stuff, and now I'm an instructor! Other teachers say I have great cueing for a newbie; and Cathe gets a lot of the credit. When you're used to greatness, you don't want to deliver anything different.
