I jsut looked at the link. That looks quite expensive. If I were going to buy something for that much I would look into the NX Ntercooler kit. not much more money on ebay and ~400 from a vender. They are proven. My fittings and copper tubing cost maybe $5. I had the lone laying around and I could get a cheap ball valve for ~5. That leaves my total to ~$10 and finding a bottle (actually I have a 15# bottle but am not sure if they would fill it. Don't know the specs).
