Do you know of any good/cheap/easy to deal with companies in Germany which do PCB fabrication for people like us?
Build them yourself!
I can go from concept to using it in a couple of hours. I rarely breadboard stuff now. It is cheap enough to make boards. You can spend quite a bit like I did but you don't need to. There are methods for laser printing onto magazine paper then ironing it onto a copper board, remove paper leaving toner in place and then etch in cat litter tray. I don't know the specifics as I have a three tank commercial setup but I know people that use this method and it works.
