Temperature controllers.

I was wondering what people's thoughts were on the various types of temp controllers out there. I will be using it on a fridgidaire 7.2 keezer, and am not finding much difference between the Ranco, Love, and Johnson brands.
I would like to avoid wiring directly if able, as this seems like an unnecessary hassle (correct me if I am missing something). So that likely means the outlet versions. Thanks in advance for any comments.

I have a Ranco and find it to work very well...if you are handy you can wire it yourself, say $50 - $60, or there are prewired versions for a few more bucks...$80 - $90.

Pretty good thread recently on adjusting the internal thermostat on a freezer...looks like just about as much work as wiring a ranco and $50 cheaper.

I built my own. Found it quite easy and much less expensive. The plans are here:

+1 on the "eBay aquarium temp controller"! It's an STC 1000 controller and its pretty easy to build. Plenty of examples on this forum. Works awesomely too! :rockin:

I love my stc, works good on my fermentation fridge and my ehlt and super cheap!

Johnson digital, plug and play.

I have Ranco and Johnson both. Prefer the Ranco for +/- 1 degree accuracy and easy set features. The probe is also smaller than the Johnson and fits in 1/4 inch thermowells. No complaints - have 3 Ranco for fermentation controllers and use my two Johnson's on my kegerator and fermentation chamber ambient control.

Another recent STC 1000 convert here. Plenty of detailed instruction, works flawlessly ( thus far )

+1 on the STC. I've made two and they work great. If your interested here's my fermentation chamber where I use both of my temperature controllers. https://www.homebrewtalk.com/f51/dual-fermentation-chamber-build-318098/

Thanks for the replies everybody.

I have a mini fridge with an, apparently, bad temperature controller. Would the eBay aquarium temp controller be able to replace the one on my fridge? I would assume I could just plug in my fridge wires to the controller and be good to go.

You just have to bypass the mini fridges internal thermostat with the controller should work good
