Temp Controller - Getting Gadgety

In our brewing sessions we mostly brew at my house (Bill's) but we also brew at Mike's.  We've consistently had a better end result in beer when we ferment at Mike's house.  Curious about this I've narrowed it down to the fact that Mike is able to keep the beer in a room with a consistent temperature the entire time while I keep having to shift the beer around to try to find a good consistent temperature due to a variety of external factors not the least of which is my wife and the thermostat.

To cure this problem I've decided to buy a temperature controller and attempt to setup a fermentation chamber so that I can keep the bucket at the right temp for the beer being brewed.  I settled on the BrewBit which is probably more than I need but I'm a bit of a gadget freak so I figured, "What the hell?"

I have a small dorm style fridge that I think will be big enough to hold the bucket (I hope) and, if so, I'll be using that as my chamber.  If not I'll have to find something better (suggestions are more than welcome).  As the controller can manage two heat sources and our weather is inconsistent to say the least I figured I'd put the fridge on it and then drop a small hair dryer in the fridge and use that as the other heat source.  The brewbit could then cool or warm the interior of the fridge based on the current situation.

The last two beers we brewed at my house just haven't tasted right to me and I've been reluctant to brew again until I could improve the environmental controls a bit.  I hope I don't have to wait too long to get the brew bit becuase I'd like to get back at it. I figure I'll do a couple more extract kits and if they work out better than it will be time to try some all grain recipes.  If that works then I have my eyes on building a keezer.
