+1 for Austin Homebrew supply. However, I will add the Midwest has done a couple of Groupon deals for starter kits that are awesome deals. Also lets not forget your LHBS. Might pay a little bit extra, but as someone who just had their local store go out of business, let me tell you that it is worth paying a little extra to have a place in town.
Sucks waking up on a weekend, realizing my day is clear but not being able to brew because I don't have any ingredients handy and the nearest shop is an hour drive.
