Oh crap, I have 3 PIDs and 4 machines..... hmmmm back to Ebay...
Where you'll find an irresistible deal on 3 controllers, so you'll have to get 2 more espresso machines so the PID's don't go to waste. It's a never-ending cycle!
You are soooooo right. I was one PID short... and got a deal on 5 new Fuji PXR3s today....
now I have to get 4 more machines..... or maybe offer a few of them up here
