I don't come on here often anymore since the truck is gone, but I figured I'd chime in. We (myself and two coworkers) are just getting into brewing and we're having a ton of fun with it. First two batches were a summer wheat similar to Blue Moon and an IPA similar to Sierra Nevada. We recently bottled our 3rd and 4th batches one being Belgium Wheat and the other a Chocolate Ale, those should be ready on Friday.
Like Gus said, we're usually into it for about 60-75 for two 5 gal batches that yields ~100 or so bottles. We also usually manage to screw them up somehow because we are inherently drinking beer while brewing and we usually get pretty drunk before the process finishes.
