Well, at this stage of the game, for me, Co2 purchases for a 10lb tank or so to run a 3 keg kegerator would cost prohibitive. So bottling it is. Priming sugar is cheaper & a 10 cu ft fridge is a couple hundred at two places where I can use my plastic. It'd fit about 18 or so 12oz beers on each of the shelves if spaced right. Then I can have 3-4 different beers in there, including a freezer for hops & space on the door for yeast & LME. So spend a similar amount on a fridge & prime, or get a keg system & keep buying Co2...
