Back from my piano shopping trip! Got lots to report.
Disappointingly the Steinway A that was supposed to be ready to go was nowhere to be seen.

The guy showing us around wasn't the owner either, so he had no idea where it was or if it had been sold or whatever. Really kind of annoyed as we'd driven 2 hours to see that workshop in LARGE part because of that Steinway! Sheesh!
Still we did see many other pianos. The following are the ones I tried and my thoughts:
Mason&Hamlin A, 1914 - very muffled sound, action felt 'trampoline-y' with far too much recoil
Steinway model O - great tone WITH the sustain pedal on, but sounded *completely* dead when playing with no pedal (Bach, Mozart). what - is this a flaw of the piano, or a problem with the rebuild?!? I really want to know as I'm still considering this shop to rebuild a Bluthner but I won't bother if this Steinway's issues are a fault of the tech. Also, the sustain pedal was extremely stiff and had very little travel.
Steinway D, 1887 - Omg this was such an ugly piano! Bizarre L shaped monstrosity. Full bass but really thin treble. Nice action, no sostenuto pedal makes it a dealbreaker.
Yamaha C7 (1970's) - it was "nice". LOL that's about all I can say. Good power in the base, but completely boring and almost clinical.
C.Bechstein 5'8" - very light quick action, but also very small sound
and finally, a private sale:
Kawai RX3 (2006) -
I do love Kawai's, and this one had a nice full bodied sound, and a heavier action which I liked. However, some serious voicing issues here. The current owner bought the piano when he started to first learn (yeaaaaaahhh, bad idea) and basically quit trying to play after a year. So basically, this piano hasn't been played at all in most of its lifetime, so I think a LOT of its issues are that it's never been properly broken in and adjusted. It's so strange - the middle and lower registers sound quite muddied, but the upper ranges are REALLY overbright,so when playing it if you cross into the upper few octaves it's just jarringly bright out of nowhere.
Also, sticky keys everywhere! An easy fix, but wow, shouldn't be happening in a fairly new piano. I was considering offering around $10k cash if I want this one, as I'd still have to pay for the move and probably a whole bunch for a technician to fix the voicing. We're going to ask our tuner what he thinks, because I'm not sure if the voicing issues are a dealbreaker, but I'm tempted as we can probably get a good price here. And it's still got a year of manufacturer's warranty left on it.
Next weekend we're going to the Kawai dealership, so I can try the brand new ones and compare. I'm also waiting for the rebuilder guy to call me back about the Bluthner/Bechstein.
