Prngr44 does some home brewing.
Yes I do!
I'm on the east side so if I need some last minute ingredients I usually hit Dave's Homebrew in Belleville.
Otherwise I buy just about all of my stuff through Missouri Malt Supply. Bulk discounts, and the other stuff's a lot cheaper.
I got hooked bad too and went all-grain after 2 extract batches. I do 10g batches unless I'm making a crazy heavy beer. (I learned the hard way that my mash tun cannot hold enough water and ~50 pounds of grain for big beers.)
