if you can understand If/Then arguments, and want a little better controller, I suggest this:
Digital Aquatics Online Store
It's an aquarium controller, and it does have 4 outlets. It's a bit overkill but for $100 it's not bad.
I have a similar one on my fish tank, and it's great.
Programming looks like this:
if temp <75, H-1 = ON
if temp >77, H-1 = OFF
If temp >81, C-1 = ON
H1= heater
C1= Chiller.
SO in your fridge/freezer (since you're fermenting) you can set your temps and be safe to ferment in summer or winter.
If you're willing to do a bit of wiring, you can get a Love or Johnson/Ranco for less, then spend the cash on parts. I have two Love controllers and I dig them. One's on the keezer and one is in my fermentation bath.
