Watch out for "gray market" used Yamahas. These are Yamahas used in Japan, traded, and then exported since the Japanese apparently don't buy used pianos. The wood is different because of humidity differences in Japan, and it may lead to problems in the U.S. Search google for gray market Yamahas. Buy from a reputable dealer. You want a Yamaha made for the U.S.

If money is no object, get a Steinway. They retain their value best. A good used upright < 10 yrs old can be had for $!5K, if you can find one. You can always resell a Steinway. They are like a Porsche.

Grand pianos sound better than uprights, and are a better investment if you have the room.

You really need to have someone with you who plays and knows a good sounding piano from a bad one.
