Lagin--
I was going to leave this one alone, but after several days I see no one has replied to you.
All I can say is, my piano was manufactured by Samick. It is actually a "Howard by Baldwin." Samick manufactured these pianos so Baldwin could sell them as a second line back in the 1990s.
I really like my piano. I'm quite satisfied with it. I think it sounds good, and it is trouble free.
I am sure Samick makes some good pianos. They are not a premium line, and I"m also sure you can get better pianos by paying a lot more.
If the piano sounds good, probably the exact size of the upright is not too important. In a small living room or parlor, even a small piano will produce good levels of sound.
Others are better to answer this, but at least you will get one reply.
