I know this thread is kind of on the older side, but I wanted to say I like the mini-kegs. Aside from being a bitch and half to clean sometimes, they are really cool if you are big into bringing your homebrew outside the home. I for one like to bring it to family functions since whenever someone says bring a dish to pass, our invite always asks if I can bring some of my beer. Each keg is roughly a 12 pack and I have a mini-keg tap box that holds 2 mini's. I keep it in my fridge as my tap the rest of time. They must be keg conditioned like a bottle but once you figure out how much priming sugar to use it's a snap. Plus, if you keep pressure on the keg you don't really run into overcarbonating, if anything some people tend to have it undercarbonated. But with practice, just like your brewing system you tend to figure out your mini keg system as well. But I want to say that if just having your beer on tap at home is your main goal, just go with a regular kegerator. Many people have built portable bars and jockey boxes for the 5 gallon corny's but I wouldn't want to lug those things around if you take your beer places often, which is what I do. I don't like to keep tabs on bottles and such. I guess what you have to do is look at what you really want kegs for. For the most part I bottle half a batch and mini keg the other half.
