Hello, after some years of inactivity I'd like to restart playing piano. I played (and sometimes studied) it for 20 years; I like jazz; To restart I found a yamaha p90 on internet at a good price. What do you think about this piano? Is it still valid in comparison to other new Yamaha models (P85, Cp33)? How is the p90 keyboard action? Help me... I would not do a wrong choose! Thank you Emanuele
