Which Love temperature controller?

I'm doing a keezer conversion and would like any advice anyone has on which love (or other panel-mount) temperature controller to buy. What are the benefits and drawbacks to each TS, TS2, TS3, etc.

I have an anaolog temp controller that does what it needs to do. Simple and great. I loves it.

 

Yeah, I currently have an analog one too, something like this:

I'm trying to get a more integrated, better looking setup, something like this:

So I'm looking to upgrade my temp controller...

 

I used a Love TS3 for my Keezer and it's working great. It's $50 at Dwyer without the probe, which is a great price compared to some of the other Love controllers that are used for a keezer.

For my fermentor I used a Love TSS2, these have 2 relays for heating and cooling.

 

Thats the one I have. The first one. Quick n easy. Does the job
