I need a fridge for my fermenter, any recommendations?

First, unless you plan to finish a keg before you start fermenting your next beer, you're going to need two.

For both, I'd recommend looking at chest freezers. They can often be had for peanuts at garage sales or on Craigslist. There are hundreds of models to choose from...just make sure whatever you get has enough floorspace for the maximum number of fermenters (or kegs) you plan to put in it, and is tall enough for same. (Be sure to include the height of any hardware attached to the top of your fermenters (or kegs). For a keg freezer ("keezer"), think about whether you want to use picnic taps or proper faucets. If the latter, google up "keezer collar" to see the best way to accommodate that. (A collar also allows you to get away with a shorter freezer, because it increases the height when you add it.

You're also going to need a temperature controller for each freezer. For the fermentation freezer, you might need a dual (heating and cooling) controller, plus a heat source (fermwrap or whatever).
