The best distributor I've found in the area is on Court & Kane Sts. in Brooklyn (Cobble Hill) - American Beer Distributing (aka Thrifty). Call them at 718-875-0226. Whatever few beers they don't carry can generally be special ordered.
And speaking of Sierra Nevada, try their Celebration Ale this year. It is an outstanding hoppy holiday treat.
