What's the reliability of that CC1 v2? According to the internet, the Gaggia and the Lelit score well here, but not much info on the CC1. Also, why does that one steam milk better? I know my wife would be making milk drinks.
I had the Lelit set up with a PID for a while, but I stole the parts for another project (greenhouse heater).
Basically you interrupt the built-in thermostat with a solid state relay which is controlled by a PID module and connect its thermocouple to an appropriate spot on the boiler. I used matching spade terminals, so it's totally non-destructive. Parts run about $50 if you look around and it's a really easy project.
I can confirm that the single boiler machines all suck for steaming milk. This is especially a problem if your standards are high for cappuccino, as the milk must be steamed as the shot is pulling for the texture once you mix the two to come out right. This is also true if you want to do latte art. The simple fact is that if milk drinks matter to you, the entry fee is much higher. No one would recommend a $900 bike for riding A-Line at Whistler--there is a certain minimum required to play the game.
(I've gotten out of the business, but in a past life I trained baristas for a 6 cafe chain and then roasted professionally, first on a 90kg Probat (3000# daily) and later on a 20kg Probat while supervising the guy on the 90. It was a fun gig, but making a real living in the coffee industry is hard, and I like to travel for long stretches.)
If you want to do milk drinks for cheap, another option is to run 2 small machines. Set one up for making shots and leave the other one for steaming. The little guys can only really steam about 12oz though of milk before they, uh, run out of steam.
