Hi - I had returned to piano for the past year, taking lessons and practicing daily. I feel it's time to upgrade my existing piano, which I first received when I was in junior high and sat unused for a number of years before I started playing again. I've had a technician look at my existing upright piano (Schafer & Sons) who did a tuning. After a year of consistent use, my piano how is noticeably sluggish, the pedal makes a noise, and the lower notes don't sustain. I've begun visiting showrooms to look at new pianos and occasional used upright pianos. Cost is a factor in my decision but I also want a better playing experience with richer sound and ability to control dynamics. I've taken a look at a few Yamaha options (U1 and YUS3, plus a baby grand), a vintage Schimmel upright from the 80s which had a nice action but I wasn't yet sure about the sound, Essex (didn't like the action), Boston (sound was ok but didn't love it), and Steinway upright (too expensive). Since this is my first time buying a piano, are there any suggestions on which could be my better upgrade without breaking the bank? At this time, any of these would be better than my current piano, but would like to know what I should weight into the factors of deciding.
