Starting with a one gallon fermenter is too small to almost be useful. If you're looking to get 3 quarts of finished, undiluted mead/wine/cider, then that is fine. I start my 1 gallon recipe out with about 1.5 gallons total. After primary is finished in the bucket, I rack to a 4L Carl Rossi, like the others said, then rack again to the Rossi, then on the third racking, I'll start going to the gallon containers. Otherwise, It's not really worth the effort to get at most 3 good bottles.
Edit. Maybe I should clarify some more. I use a lot of fruit, so I'm guaranteed to lose volume. If making a mead using only honey and other sugars, perhaps a 4L primary will suffice. I still think it's a bit too small, but if all you are losing is yeast, it may be good enough to rack down into a one gallon jug.
