$20,000 dollars in equipment? How the hell do you do that? I feel like I'm pretty well set up and I've got about 1/20th of that invested and I feel like I'm pretty well set up and brewing some fantastic beer.
No disrespect but i'm going to guess you and I may be at a different scale. I have a pretty nice rig, a large investment in measurement tools, and also significant storage capacity.
