I used to get mine in a liquor store that specializes in presenting a wide variety of beer. I would look online to a store near you.

It outcrops on eBay with some frequency. Are you sure you want a brew and not a kit for home brewing?

If you are interested in brewing (5-15 gallon batches), then consult a local homebrew shop or online at http://www.midwestsupplies.com or http://www.austinhomebrew.com

If you are interested in the heavy equipment (actual size microbrewery), then check http://probrewer.com
