I had always wanted to try it, but it was SO expensive! I found a site...
www.acne.org.
Go there and they have a great plan. It is EXACTLY like proactiv, but it is using individual products, not a group. Products you buy right from the store. Neutragena, Cetaphil, etc, etc...
You are using the same active ingredients! It has worked well for me, and it isn't nearly as expensive!
