Now, can we pressure you into a little bit of patience?
You'll have a much, MUCH better product doing this the right way, and giving it enough time. You'll have something to get you buzzed that's also pretty high quality.
Depends on where you buy it. My last 5 gallon was $23, I think, at the HBS. My 3s were $20, I think. Don't always have the luxury of waiting for a garage sale or for something to show up on Craigslist.
