Good Sized Kegging Fridge

It's more energy efficient than opening a fridge door. In the freezer cold air doesn't pour out since the opening is through top. Picnic taps are fine...they work very well. Plus, you don't have to spend money on a collar or tower + the faucets. If u change your mind later it is an easy upgrade.

I don't mind bottling.  There's a lot of convenience in being able to give bottles to friends and family, bottles that have quality carbonation.  And if it's something you want to age, like a belgian, saison, stout, or barleywine, you can keep portions around easily without worrying about tying up one of your kegs.  I still have a few bottles of a stout I made a year ago (not a particularly good stout, but still).  I'm happy to have one keg for our events, but I think I'll pass for a while on getting any other equipment.

I too was sick of bottling after only a few batches. I at first looked into getting a used mini-fridge and doing the conversion myself, however the lack of tools I own and experience with this sort of project led me to purchasing a used kegerator unit. I ended up getting the Danby model for $260 which came with the 5lb tank and regulator and all the hoses. Only things I had to buy were the Corny kegs and disconnects. All in all I think I got a pretty good deal and now have a draft set up for a few hundred bucks.

If you go online through kegworks or Midwest, they have fully assembled kits with everything you need.  That route is usually cheaper then buying everything individually.  

And, now that i've had a little time to think about your original question, you could invest in a cold plate instead of a fridge.  In this setup you keep your keg wherever you need at room temp.  The beer line is then sent through the plate where it is chilled and brought down to drinking temp.

here is an example : http://www.midwestsupplies.com/cold-plates-double-line.html  Ebay has these for much cheaper too.  the cheaper route would be a stainless steel coil, which would do the same thing from Mcmaster-Carr

For me..I hate bottling...to labor intensive and storing all those cases...plus I like having my brew cold on tap...

here is a link to my thread showing my keezer build...I found my keezer for $80 on CL and it is a 5.0cu. With a 8" collar it can hold 3 corney kegs...now my collar I made out of solid maple$$$...but you can do it out of pine and paint it...I also installed a love controller, but a RANCO works good too....of course...I love projects and be more then happy to assist...

Here is a 7 cu ft freezer I just found on CL for $75

FYI, you don't necessary need a fridge or freezer to convert to still use kegs.  You can transfer your beer into a keg, carbonate it, and then simply store it somewhere.  Putting it in the same place you ferment isnt a bad idea.  You'll want to keep it somewhere that doesn't have drastic temp swings.  When you're ready to start drinking it, put it on ice.  Or if you want to spend a little dough, buy a keg glove with an ice pack insert.  Serve and enjoy.

If you're looking for a way to serve over a longer period...you're gonna have to invest a little money.  Be patient, and keep an eye on Craigstlist.  Find a good used fridge and convert it with some taps.  I can help more in this area if you go that route.

As far as the space issue goes, try to find a smaller mini-fridge.  You can usually fit two corny kegs into the taller type fridge.  I'd also recommend a small freezer too...like bill mentioned.  The freezers are more energy efficient, but will require a controller to bypass the internal settings and put the freezer at a temperature range suitable for serving beer.

There are costs associated with kegging...but I love pouring beers from draft.  And who really wants to clean and disinfect two cases of bottles, then fill and cap each one.  Kegging is one transfer.
