When I started my build, I started a blog to document the process: http://makeitstout.com/.
In summary, I brew in a bottom-draining keggle. I heat with a 240V electric element, regulated by an integrated control box built from a kit from ebrewsupply.com. The entire apparatus is contained in a home-built cart that I can wheel out to set up and put away.
Instead of squeezing my grain bag, it set it into my old mash-tun and let it drain into the kettle while I bring the wort up to boil.
I have a Chugger pump I use to circulate the wort for temperature regulation during the mash but also during chilling (I currently chill with a 25' immersion chiller - this is next on my list to upgrade).
I ferment in a 30 year old side-by-side fridge that I acquired for $50. I use a typical STC-1000 to regulate temps.
All details of my build (including where I purchased all components) are in various pages of the blog, but if anyone has any questions, please post away. I will update this thread as I continue to tweak my design and upgrade new equipment.
