Chest freezer from Costco + temp control = $200 is the way I went.  I tried looking on craigslist but trying to find a non-rusted/quality refrig for under $200 wasn't available.  I tried a standup freezer but the selves didn't work for the carboy.

My opinion is to get a good refrig so you can upgrade to a conical later or don't need to lift the fermentor up as high.  If you're on a budget and can't find a cheap refrig on craigslist, I'd go for a chest freezer.  Negative for the chest freezer is lifting the fermentor ~4 ft to get it out.

I have two converted chest freezers and a fridge I use as fermentation chambers. You need temp controllers on everything AND your chest freezer will need to have a fan inside with a tub of DryLock. Chest freezers typically will have condensation form inside due to the freeze thaw cycle, and you'll get rust and mildew form in the unit. A fan recycling the air will stop the water issues. Your beer will turn out great.

Why do I see a lot of videos of people taking insulation out of the 'fridges and freezers?

Wow, I've never even heard of that!  I use a 14.8 cu. ft. chest freezer with this controller...

Denny, does your temp control turn  heat and cooling on at the same time, or do you have to switch between a heating and cooling mode?

My approach is a separate insulated box that is ducted into the freezer compartment on a top-freezer refrigerator. The freezer works perfectly and holds all my hops and the refrigerator holds all my kegs. The chamber temperature can be varied between freezing and 70F. A muffin fan from a computer is inserted into one of the ducts and a Johnson A419 controls when it operates. I use a 12 gal conical in the chamber and since the chamber is elevated, I just open the tap on the conical and drain the beer into a waiting keg sitting at floor level. It really has been a good system.

That is one badass rig, Martin. Brilliant idea!

How do you run the temp control wires into the fridge or freezer typically?

Mine has no modification, the lid just closes on them

+1 - This might be easier for those of us with chest freezers, since gravity is holding that door closed & sealed.

+1 to Martin's system. I have never seen that done anywhere. Totally efficient use of space. Awesome design.

Denny, does your temp control turn  heat and cooling on at the same time, or do you have to switch between a heating and cooling mode?

Well, not exactly at the same time, of course, but there are set points for both heating and cooling.  I plug the freezer into one outlet and a reptile heater bulb into the other and the controller activates whichever is needed.  You don't have to reset anhyt8ng in the controller. Lots of cool features like a delay so the freezer come back on after it's just shut off.  The manual is here...http://auberins.com/images/Manual/TD100.pdf

Thanks, Denny! I almost bought one at my LHBS, but they told me it had to manually be switched between heating and cooling. Since I work 10 hours shifts during the biggest temp fluctuations of the day, I needed to be able to set and forget while I'm at work.

Saw this today, looked like an affordable unit, plenty of space for my ~8 gallon fermenter. Thoughts?

1 - check out Homebrew talk for a thread on the capacities of various freezers. Many of the more commons units are on there and this one really awesome guy has drawn diagrams of what fits. Great resource.

2 - I am a firm believer in never buying an appliance at full price. Keep an eye out and pounce when the price is right. I got my 8 cf freezer on sale for $210 a few years back. Full price was ~$300.

If you know somebody that has recently moved, the change of address packets normally come with lowes coupon. 10 or 15% off
