I am looking to buy a used Upright Piano. I did take a look at PianoBludeBook and figured that a 48'' Upright is the best and followed by Studio. I have shortlisted a Samick (46'') Upright , Henry F Miller (UP118M , 46''). Would anybody guide me on whether these brands are a good buy? I talked to a local Piano Tuner and he said these are American brands and only have 3 points? What does he mean by them? His only recommendation was the Yamaha U1 upright Piano. Please suggest on how should I proceed? Any feedback on the Samick and HEnry F Miller brands? TIA
