David - the Fazioli has a great reputation but all the pics I have seen it seems a bit over the top in ornate design. Never seen one in real life.
But for OTT have you ever seen, or even heard of the Borgato piano from Italy. They are hand built by only Borgato himself and one other craftsman, make only max 2 per year and cost about half million dollars upwards, which makes even the Fazioli seem like a bargain. They are also sometimes supersized, with huge long keyboards with about 100 notes, and some with two keyboards and 14 pedals!!
I read some reviews by concert pianists which said the sound and feel is amazing. At half a million it better be.
Like you though I like Kawaii. Did you know that he started with Yamaha, helped develop their pianos, then broke away. The two factories are close together.
