Have you ever seen the movie "Field of Dreams?" you know the part where Kevin Costner is hearing the phrase "Go the Distance" in his ear?
Buddy, it's time.
Get yourself a keg fridge, a 5 gallon corny keg, a 5 or 20 pound CO2 tank, and all the fittings, and get that beer kegged and carbonated. Your friends are relying on you. What's going to happen when NYE rolls around, and they say Ty! Ty! Where's the beer? And you say "Aww geez... sorry guys, can we celebrate New Years on the 12th? You see, my pansy ass wouldn't take the plunge and get a kegging system which would allow me to give my beer the repect it deserves by serving it on draught. Not to mention the luxury of force carbonation so that my bad-ass beer would be ready for you a week before NYE instead of a week after.
Ty, this is an EMERGENCY. If you have a wife, just explain it to her that way!
It's beer my brother! BEER! And it NEEDS to be ready for NYE!
In all seriousness, you can get a fridge on craigslist for 50 bucks. Any self respecting homebrew store would have a used corny keg and replacement gaskets. Wherever you live I'm sure has a source of compressed CO2. I woudn 't dick around with the mini kegs any more. Go the distance, my friend. Make the investment. It's only the 17th. I will be happy to give you more detailed instruction if you decide to put this thign together. I have 10 cornys and just use picnic taps, so it doesn't need to be fancy. It's a one-time investment of only about 200 to 300 bucks. It stings when you shell it out, but boy, does it make life easier from then on. Good luck with whatever you decide!
