+1 for Austin Homebrew Supply.
They have a great selection, a great deal on shipping, and are really nice people to deal with. Additionally, Forrest, the owner, hangs around here and is holding a sale this weekend just for HBT folks. As someone with not-so-great LHBS options, I like the fact that AHS is part of my community in a way, and I've found their prices and service to be pretty excellent- their hop selection at the moment is near-miraculous. They don't even pay me to say this stuff.
