Evening all. There is a relatively new supplier here, he's been going for a while but has only just launched his website. He makes smoke units and a range of steam engine boiler and engine controllers. I have one of his boiler managment units and must say he does an excellent job and will help with set up via phone and or messenger video.
NB I have no connection other than being a satisfied customer.
