You can still purchase Dreamflex from Performance PCs. I had used Dreamflex for several years, and decided to give the Primochill a try. I still had some Dreamflex on hand when the Primochill arrived, and I found the Dreamflex better to work with, and able to make tighter bends without kinking. The other thing about the Dreamflex that I loved is the outside finish - very easy to use with compression fittings, while the Primochill "sticks" when you are tightening and can turn with the fitting. I also never had any plasticizer issues with Dreamflex, but I did always change it yearly. I have since switched to Tygon Norprene, but if I was going back to a plastic, it would be Dreamflex.
