+1 on kegging. i angered the beer karma gods and jumped straight to kegging when I started brewing. (I know, I know - I cheated; I was supposed to pay my dues by bottling first.) All that bottling then waiting seemed like way too much trouble for me - not to mention skipping the cost of stocking up on bottles.
Now, thanks to
BierMuncher's Better Bottle Filler, I've got the best of both worlds - I can fill up a couple bottles on the spot and send people home with some brew, and have it on tap at the same time. That's a long thread, but worth the read. Basically you cut a racking tube, put it through a stopper, attach the other end into a picnic tap, drop your pressure to 5psi and keep the bottle under pressure as you're filling it so as to retain the carbonation. Super easy, super quick (once you do it once or twice and get a feel for it).
If you have a spare fridge, all you'll need is a CO2 tank, used kegs and tubing. Get 3/16" ID tubing - known as "foam free" because of the extra internal resistance it offers and the reduction of foaming at the other end. It still needs to be several feet long, though.
Check out this post (the Excel file attachment) for a very convenient calculator that takes all the sweat out of getting the right length of line for a proper pour.
Once you get to the keezer stage, definitely go with Perlick taps. They're more expensive but way worth it. You'll eventually wind up upgrading; may as well save yourself the cost of the cheap tap (and the aggravation).
Lastly, I'd suggest getting a chest freezer off of craig's list. You can use one of those minifridges if space is tight, but it'll wind up being more expensive than a chest freezer and you'll have less room.
The extra room is great for 2 reasons: First, I always keep a keg of sanitiser that I can plug my lines into and flush em out lickety split, easy peezy. Then I use that keg for my next batch - it's clean, pressure tested and ready to go! Second, it sure it nice to be able to cold crash my secondaries before racking into the kegs!! Clarification without the chemicals.
I Got mine for $30 off of craig's list - a fraction of the cost of a new one. It looked like hell when I bought it, but a little paint and my Ravens keezer is rockin!
Good luck!
