I think I'm going to cave in and buy a Sanyo 4912 with an external thermostat to ferment in, the temperature just varies too much here in Texas and it's too hot 90% of the year. I've been looking on craigslist and such trying to find a used fridge and even debated about making a fermentation chamber I see so many people using on the net, but I'm looking for a set it and forget it solution. I don't want to have to change ice bottles, replace water, or any of that, just something simple. Plus I can always revert to using the fridge as an actual fridge for my beer when I'm not fermenting. I figure if I'm going to be serious about brewing, I need something to maintain good fermentation temperatures. So my question is... do most of you all use a fridge, freezer, home made contraption, leave it at room temp., or what?
