Yeah, local AC shops will screw you with $50/lb rates, but nobody has to pay that if they know where to look. You can get R-12 on eBay for more like $20/lb, in cans or tanks. I still recommend staying with R-12 if possible. Duracool won't work well at high ambient temps (Arizona, Florida, Texas, central CA, and anywhere else it gets over 100F). It does beat R-134a though. Remember tha Duracool is ILLEGAL to use in motor vehicles in about a dozen states. Personally I don't like the fact that their website has very, very vague & sparse technical information, especially when compared to the Autofrost site. I think I'd rather use their product (Cooltop, GHG-X8) instead of Duracool but that's just my opinion.
