Pleased to hear you own one of these engines Daniel, they are good aren’t they!! 

Out of interest how many of Kontax’s engines do you own in your collection?

That Inpro Solar sounds interesting, I’m guessing it is very similar to the Kontax solar offerings?

Howdy Philip. I'm afraid the Nano is the only Kontax that I own, but I'd certainly not be adverse to owning others, based on this one's obvious qualities! It seems that the German Inpro Solar low temp Stirling kit may be a bit of a disappointment after looking at it some, but I'll reserve final judgement until after I get it up and hopefully running. It doesn't seem to be as nice a build quality as the Kontax version looks to be, but time will tell.
