I added a spigot near the bottom of my fermenting buckets with 2ft of 1/4" hose and a black ball lock at the end. If I sanitize my kegs along with the fermenters on brewing day then when it comes time to rack the beers I just swish the ball lock in a little boiling water, attach the ball lock to the keg and watch the goodness flow. Does it get any easier? Maybe, if you get someone else to do it for you.
I still bottle a few sixers direct from the keg (for gifts or to age), but for short trips growlers work just as well.
That is a brilliant idea. Now if I fermented in bottling buckets I would seriously consider that.
