So I made the switch from bottling to Kegging about a year ago, my suggestions:
Facebook and Craigslist are realistic options for equipment, kegs, taps regulators and Co2 tanks are a lot less.
I have a Edgestar.com kegerator, that I built into my existing bar with a triple tap, if I could do it all again, I would have gotten a chest freezer with mounted picnic taps and an external thermostat..but the bar was built 20 years ago.
I bought the model that can fit 3 (ball-lock) corney kegs... figure out ball or pin lock, 1/4" air hose or 3/8" air hose
honestly, I have 5 kegs, the one I have the most problems with was the newer style one, all of the converted soda kegs have been champs.
Remember, though you are not filling bottles, you are washing kegs, cleaning lines. buying CO2 and fixing leaks (beer and Co2), this does not eliminate all the work.
Finally, go slow. Think about the system and how you are brewing though our the year before you load up your credit card with equipment purchases.
Get one keg, a 5 lbs Co2 tank, regulator and picnic tap.. on craigslist that would be about $80-100 over here.. see how it works for you. I still bottle some of my beer (I have a few cases of flip tops, that makes lifer easier)..
