Haha, i got rough with the Yamahas there, i don't actually like the C ones, i did tried them at some school and i found that it doesn't fit my playing style, maybe it wasn't well regulated, had only chance to play it 1 or 2 minutes, didn't ask about it. Sorry Yamaha.
The concert hall where i live has a Steinway model B which i believe it's a tad smaller than the D; i have used that one a lot, i found it had a warm sound and the action was satisfactory(relying on memory here).
Seriously I don't know about Baldwin at all, school has gotten hard lately and the closest piano store is about 10 hours by bus so i am going to get a chance in vacations to do all the research possible.
About Bechstein, i think it was a C Bechstein i saw and i like it's sound, haven't played them actually.
