I really wish tyour controller had been available when I was contemplating the "souping-up" of my Rancilio Silvia espresso machine. The PID I have is one that Auto Tunes to the application. The different outputs were not available. Mine is an Omega. It is like the Love control and here is a picture of the one I bought.

I never installed it. I picked up a Commercial Espresso machine and decided to sell off the Silvia, and thought it best to keep it stock. I am glad I didn't modify it. If I decide to retire soon, I am going to pick up a used Prevost Bus/RV conversion, and the heck with just coffee on the road. I will just install the espresso machine and the Rocky Grinder somewhere in the galley of the bus.
Quite the coffee snob, I roast my own beans, and just cannot stand restaurant coffee, nor the crap they sell at Starbucks which is alledgedly "fresh." Boiler control for the perfect shot of espresso is crucial, and the PID was the solution so many have used to make their espresso machine sing!
The new machine I bought can pull 40-50 drinks an hour were I ever to need to do that, and the boiler is not a problem.
Check out my set-up:

For those who want to infinitely control the temp of their Bradley, and don't want to constantly be outside sliding the switch, this is a good solution.
I have the Procom4 and Raptor setup, and love it. I love it because I can tweak the cabinet temp from wherever I want in the house or on the property. If I am lounging in the pool, my controller is in a waterproof bag, and I always know what the temp of the cabinet(s) is/are, and can up the heat remotely, or just let it run and control temp until the meat reaches the desired temp.
With the new electronics, I am sure someone will come up with something that works. I don't think it will better than the Procom4 setup, but I am sure it will be a lot cheaper.
I have no regrets about forsaking the constant sliding of the switch an opting for the capability of remote monitoring and control. I wish it would have been cheaper, but what the hell, buying toys like this is a benefit for still working even though I have retired twice.
I do love the toys!
