A Bentley was my first piano as a child. My parents bought it following the recommendations of the shop owner who waxed lyrical about its beautiful tone. Personally I think what attracted them to it was its small size. I have not played in it for over 30 years, but I recall it as being bright rather than dark in sound, and certainly the keys where not overweighed - if anything it was a very easy piano to play and very responsive to touch. It had a very beautiful pearly sound, and I think my parents really lucked out when they bought it. Now I may be completely wrong here, but a few years ago I was in a piano shop helping a student to choose a piano, and as I was talking to the dealer (while the student was lookng at tediffernet pianos), we started talking about Bentley, and he told me that they still existed but under a different name. I think he said "Kemble", but I cannot be sure. I hope this helps.Best wishes, Bernhard.
I used to have this awful upright where you would have to bang on the key just to get AT LEAST a pianissimo. Now I have a grand, and it is so much better! Although, the experience earned from that upright is pretty valuable, as your hands get used to the piano, then you get a new, easier to play one, your hands feel like they improve dramatically!
