I have to agree, brewing it yourself, especially AG, is about as cheap as buying, if not cheaper. For my next batch, 5 gallons, I got 10# pound of grain, 4 oz of hops, and my yeast for 15$. Tell me what IPA your gonna buy that cost 1.66 a 6 pack.
A lot of it to me, is also the princple, as well. And like I said before, times changed for me. Now, 15 bucks is a big deal to me. I know some people may say, dude, its 15$, suck it up. But, it really means a lot to me now, and is harded to come by. (disclaimer, again, I'm not complaining. It's my choice, and I'm happy with it)
