I would avoid flying bison. They make extract beer, and while I made extract beer for quite some time, theirs is not very good. I knew someone who worked there for awhile and he didn't recommend it either.
Look up Consumers Beverages. They have a decent selection, and some of the bigger stores have growler fills. I used to go to the one in Orchard Park, but it wasn't that big. I can't remember which store, but I bought my first ceramic top growler there, and the unique handle and design still get compliments many years later.
Also, a friend is involved with a pub (to be brewpub) Gene McCarthy's. Close to the highway, decent tap list for a growler fill. Check out the website for what is on tap.
