My first purchase was Mega Step through Collage. Remember the catalog came through the mail? I would pour over it with my highlighter trying to decide what to buy (no video previews)! I had been doing Power Step by Reebok but the intensity of Mega Step sold me on Cathe (all those ricochetes and the butt blasters). So sad that excitement is gone. I don't think any instructors are still making DVDs. Hoping for news on a new "download" series soon.
