Agree with perfect_pitch, the Shigeru pianos I've played were sublime. The most responsive action I have ever played.
Erm... a little out of context. I said that Shigeru were better than your standard C brand Yamaha pianos, but they're not that brilliant. Fazioli are far superior to Shigeru's; almost to the point where I feel that Kawai were trying to emulate the action of a Fazioli.
Lot of good info said alreadyIf you plan to keep it or trade up to steinway grand later , get the new boston , if instrument will see heavy use the warranty had value here . Trading in within your timeline to a steinway will be a key reason to stay in the program and so thinking long term what model you'd want in the future will let you back into the costs you're willing to tolerate now
