Most CP books have a list of CP suppliers in the back. I think many
beginners get started by purchasing from these companies, and they'll
find that PP's is probably the only listed company still in business.
Possibly as more people get on-line more will consult on-line references
before hitting the books (hmm, now that can be a scary thought! :-)
I agree that education of all parties is the best way to go!
