I'm curious to see what you can find, since I've been looking around randomly for a little bit now planning future expansions. Plenty of places seem to carry the regulators, but I've got no experience on which are of any better quality. So far the cheapest regulators I've been able to find are at
Kegconnection ($45 & $60),
Rebel Brewer ($54) and
ChiCompany ($40). Northern Brewer, Austin, Morebeer, etc. all carry regulators too which might be of higher quality, but I can't tell just by looking. Kegconnection also has a fairly cheap 5lb
nitro tank ($80) and
ApexBrew has one for $70 but they caution that not all places might fill it up.
As far as faucets, your guess is as good as mine. I've been able to find a bunch, but I'm still trying to figure out the best way to go. For instance, ChiCompany appears to have the
largest variety of stout faucets (I count 8). Of those, I see a variety of all-chrome ($66), chrome/stainless ($92), all-brass ($77), brass/stainless ($92), and all-stainless ($137). Now I'm not sure what the chrome/stainless actually implies as to what the beer actually touches along the path, does it contact stainless the whole time or chrome for part?
Adventures in homebrewing also lists a "SS Stout Faucet" for $70, but it looks a lot like the ones listed at
Morebeer and
Rebel Brewer that list them as the chrome/stainless version or the
Kegconnection one that doesn't list the metal (but I bet they'd tell you with a call).
Maybe by the time you figure everything out, I'll be able to start and can just use your list
.
