I bought 50ft 3/8" copper on ebay, $45 shipped. Wrapped it around an 8" sono-tube. Made a 30' chiller and a 20' pre-chiller. About $15 worth of brass hose fittings. Pre-made chillers were just too small (short) for my brew-pot.
that looks nice... I bet my would make the top 10 of the most ugly chillers, but it gets the job done so whatever lol!
