Hi! I am looking to buy a used piano and while I was searching online, I got the idea that Kohler and Campbells were not that good. When I went to the store today the guy said that they have improved and are now as good as Yahmaha and Steinler. At the store it sounded really nice but I don't want to buy it and find out that it is not as good as it seems. Any info would help. Thanks!
