And I feel just the opposite. I kegged for about six months and got tired of the nasty keg cleaning and the constant sticky cleanup of all the little squirts and leaks due to the hooking and unhooking of the keg lines. I'll admit that it's very nice to be able to just dump a batch straight into one container but for me, the real work began whenever the keg was emptied. Nasty, sticky beer all over the damned place. I went back to bottling because I'd rather put a tad more work in up front than at the end. Up front I had more motivation. LOL!!!
With picnic taps, I don't have beer anywhere but the sink:
* Unhook gas, carry keg to sink, put top of keg over sink, depressurize, open, and rinse.
* Fill it with hot water + oxyclean; invert a couple of times over the sink, charge it up slightly, and run oxyclean through the tap. Wait 30 minutes, invert the keg again, and run the tap briefly again
* Wait 30 minutes, empty keg, and repeat the last step with a half gallon of starsan instead of a full keg of oxyclean
Now you can take off the picnic tap and put it on the new keg in the keggerator.
Leave the starsan in the slightly pressurized keg until bottling day, when you'll open it up and rinse with fresh starsan before filling.
I'd imagine that with in-place taplines, you'd need some sort of drip trays both under the tap and to drop disconnect in while you take the keg to the sink and back, but you'd still want to clean and sanitize the lines the same way (hooking the keg back up to do so).
