By the way, with regard to the follow-along visual lights above the keys, this feature shows you what key to press when playing along with the built in songs and it will even wait for you to catch up. That is a fun feature and can be useful in the beginning for adult students and children of all ages. But at the end of the day, teachers generally don't like those things and it can create bad habits for younger students who take lessons and want to progress upward into new skill levels. However for adults (and very young children) who just want to play for fun and get music out of the piano as quickly as possible, the follow-along light system definitely makes that happen.
You can certainly be happy with any of the Yamaha CVP pianos and they are fun to play. But once you get into that price range you should also consider other options just to be sure you are making the right decision.
