New Belgium makes some descent beer that you can basically buy anywhere, but i'm still a fan of my local micro.  I get 5 gallon kegs for ~$50 which isn't bad considering premium beer on sale is typically $13 for a 12 pack (roughly a gallon).  Besides,  beer tastes way better out of a keg than it does out of a bottle or a can.  If you're ever in Reno go to Great Basin Brewery and have an "Icky" (short name for the beer Ichthyosaur which is named after the Nevada state fossil).
