Mr. Beer is how many of us got started. It gets my vote because it takes up so little space when you're not using it. (I stored all my gear inside the empty vessel). It's also good to have around for small, experimental batches, so it never truly gets retired even when you've moved on to larger All-Grain batches. My favorite thing, though is the tap on the Mr Beer Keg. Once fermentation is done, you just prime the bottles with table sugar and dispense the beer from the tap right into your bottles and cap and condition for a couple of weeks. You don't need all the extra equipment other than sanitizers, a hydrometer, a thermometer, and a capper (and crowns).
