Beer fridge

Like most guys, I have a beer fridge in my garage. I always think about buying a keg-erater but for now I just have a fridge. I replenish the fridge when needed but sometimes I face a dilemma when restocking. Do I buy the beer that I love and just have tons of my favorite brew or do I buy a mixed supply. The mixed supply allows guests who may not share my tastes to choose from a selection of beers while the latter forces my tastes on them. Part of me wants to be a good host but part of me wants to have the beer I want whenever I want it.
