I'm in the market to get a couple of kegs and a couple taps bit not sure of the best way to go ? I would like to have at least 2 beers on tap but imy neck of the woods we travel by 4 wheeler if the party isn't at my place. Just wondering what's the best bang for my buck and if I could just fill a dozen bottles out of a keg and cap them for the ride? Also are old corneys better than new ones?
I've recently bought all the components I need to make a kegging system. It was shockingly expensive - even when I took advantage of sales and bought the kegs themselves second-hand. Granted, I live in Canada where everything seems more expensive 'just because', so you will likely fare a little better than me.
What I recommend is this - buy corny kegs second-hand. I went for ball-lock kegs because their taller size means a smaller diameter - I can fit more of them in my fridge.
I bought a brand new 10# Co2 tank and dual regulator - I got them on sale. I'd strongly encourage you to check out the second hand market for these (5# Co2 tank is good too). I would have bought second hand had something been available when I pulled the trigger.
You'll also need gas hoses, beer lines, fittings, etc., and even a manifold if you want one gas line out of the Co2 tank to branch into more lines (say if you want to be carbonating a keg or two while simultaneously drinking from the others).
Something you'll need to make a major decision on is the faucets and shanks (part that connects the faucet on the outside of the fridge to the beer line on the inside of the fridge). Generally the faucets tend to come either chrome plated or stainless steel. My casual research suggested to me that I'd be happy paying the extra to go all stainless steel (for both taps and shanks), but you might be happy with chrome.
Of course you also need to decide on and acquire the cooling box (fridge or freezer) to fit everything in and do the necessary alterations. If you're going with a chest freezer you will likely need to build a collar and install a thermostat. Fridges and freezers are fairly cheap on the second hand market and very easy to find.
All of these things add up to a fairly hefty chunk of change. Even by being quite frugal but going with quality items, I spent about $800+ on developing a system that has 4 kegs, and 3 taps in a converted refrigerator (the extra keg is to have on carbing on deck while I drink from the others). Unless you find someone giving the stuff away I imagine you'd struggle hard to put together what you're after, even in the United States, for less than $500.
