Here is my last idea, to get started kegging and such.
The Nastalgia that was mentioned earlier seems to work well for those reviewers on Amazon. Free Shipping makes it 350 for a brand new, 1 tap kegerator. This is perfectly fine to start me off I feel. All things considered, it is perfectly fine to go back and forth between 2 kegs, correct? Say I start my Saturday enjoying my recent Red Ale but want to drink an IPA in the afternoon. Does it really do any negative to swap back and forth so long as it's not a continuous back and forth occurance?
No, but it's sort of a pain swapping out the keg connections and then hooking them up again. If there is any chance at all that you want more than one beer on tap at a time, I'd skip the kegerator above and get a two tap (or build your own out of a small cute chest freezer). You could get a small chest freezer, build a collar for it, and still have it be under $350 and have more than one beer on tap at a time.
Also, each time you move the keg, you resuspend any sediment that may have settled out so it's not ideal if you have to move the kegs around to swap the lines.
