Their Italian I think. Talking to an italian collector when I got mine, their very VERY common over there. Not too common in the UK, a few people have the recent one but their so flipping expensive! Over £2000 for the full kit.
Their like Kirby, a bit niche, people who know them love them, but lots of people who have never heard of them!
I'd not rush to get another tbh, one decent one is good enough (saying that if I see a cheap local one again of a different model of course I'd get it, but that's my illness talking there!
