98EXL,
I generally only brew in somewhat over one or somewhat over two gallon batches. I use 1 gallon jugs as secondaries, that way I can just stick a "cork" in them when they are done, saves space and cost. I also feel cider belongs in a jug. After all, they are called cider jugs. I'm really glad, too, I can't imagine filling my apartment with the smell of 5 gallons of Montrachet fermented fluids!
