I rarely search out beers at all, and if then I won't pay huge prices (not above market). My brother recently moved to NYC, so we have been doing bottle swaps, and my best friend lives in Austin still so I'll have him grab me a Jester King if there's something interesting. After trying Heady Topper, I realized all of the hype that surrounds most of these beers. They are marginally better than other beers, yet are hyped to the point that it seems like they are the pinnacle of perfection.
Having said this: if I saw a KBS or BCBS sitting on the shelf for a reasonable price, I'd grab one. I would not sit in line for an extended period of time to get a pour though. Some of my favorite beers are ones I rarely hear anyone else talk about and happened to grab off the shelf (BFM √225 anyone?).
