Option C: - four taps
I went from 1, to 2, and now have 4. I have the kenmoore kegerator (best wedding present ever!). I can fit 3 kegs and two bottles in (currently have that at the moment). I picked up a couple of pinlock kegs and converted them to ball locks, so that I use all of the same fittings. The pinlock will fit under the bumpout at the back of the kegerator, allowing 3 kegs at once. It's just my wife and I, so no need for more than that. The 4 taps allow for a dedicated nitro tap (no more swapping it out as needed). And has been said already, get the perlicks.
My crappy looking chest freezer/ferm/lager fridge in the garage, conditions all of the kegs. It has no taps (outside of an errant picnic tap or two, but not intended for serving). It is temp controlled though.
I got my 4 tap for a very nice price through Kegcowboy. Standard T tower style. Works very nice.
