Myth: Kegging is expensive!
Fact: CO2 Tank + Reg + Cobra Tap + Keg + Fittings can be had for under $200 plus applicable taxes and shipping, if you shop around you can often get it for less. This represents a one time investment. Additional kegs can be had for under $60 a pop used if you shop around. Even here in Canada.
Again, if you shop the classifieds, a used fridge can be had for cheap or free.
Recurring costs for CO2 tank fills are easily balanced by not having to purchase caps for bottles (I pay $4-6 per batch for PET caps or $3 for crown, 7-8 kegs off of one 5lb CO2 fill seems to be the going rate, I pay $28 for a 5lb fill, which means its about even at lowest average efficiency)
You'd need 60 12oz bottles for the average 5g batch, so not counting shipping or taxes, that's about $30 on average, then there's inevitable breakage with glass and so forth.
Kegging *is* more expensive than bottling to start. Long term though, especially if brewing frequently kegging makes great sense in both cash and time saved.
