Kegerators/Fermentation Chambers

I'm thinking about getting into kegging and have been looking at used refrigerators for storing my keg(s). But I've also been thinking about fermentation control as my house is pretty warm in the summer.

What do you all use for kegerators? What do you use for fermentation temp control? I've seen some of your Fermentation Chamber builds and I'm not quite ready to get into that (yet). So, do you have two refrigerators (one for kegerator one, for fermentation)?

What is your setup?

I've got our old chest freezer that I've converted into my fermentation chamber, using a Johnson temperature controller.
I also purchased (new) a small refrigerator that I use as my kegerator, drilled the door for a three faucet set up.
Anyway, that's what I've got!
Cheers!
