Try trading stuff.Ornlu said:
I brew about once a month, and have for the almost 10 years now. However, I'm a cheap skate at heart & if I can build it DIY or get it second hand I will. Regulators (well, working ones at least) is just one of those things I haven't been able to come across for less than $50 each.
I scored three out of date 15lb CO2 tanks on ebay for $3/ea, shipped. (yes, $12 for 3 tanks). I traded two of them at a retail business for a new filled 5lb tank, a regulator, sanke tap and some other fittings, then I retested, filled and kept the third one.
I also scored a free kegerator that didn't work on CL last year. All in, I got 4 (really funky) perlicks, a tank/regulator, and some other odds and ends. Took it apart, scrapped the freezer, detailed the perlicks and sold them to buy my intertaps, and kept that tank and regulator as well.
So yeh, I pretty much paid nothing for all my tanks and regulators hah. Just gotta keep a look out, but not necessarily for just regulators by themselves.
Maybe those aren't totally realistic examples, but if you find anything else cheaper than market value, you can trade up. Get on homebrew club facebook groups or other homebrew groups (homebrewtalk classifieds) and look for deals even if you don't need it.
