What I did was decide to mull things over a while and work on other brewing-related projects.
(Put a ball valve in my kettle, got a March pump and used it for the first time -- awesome! -- and built and tested a hop spider.)
I'm mulling over small chest freezers--either new or what comes up on Craigslist. On the one hand, they would require lifting carboys in and out. On the other hand, it would put fermentation on this floor, so I would no longer have to lug full carboys to and from a garage. I'd still have to stick with small batches, but I'm ok with that.
A used upright fridge or wine cooler would be a good find. I've noticed Sears sells freezerless fridges. I will set up a couple of searches to ping me when things pop up. I assume when I get this I'll buy a dual-temp controller.
Meanwhile, I'm brewing recipes I know will come out well in the 62-64 degree temps in the garage, and considering a brew belt to get my Belgians tasting like Belgians.
