I've been searching for digital pianos for my nephew, who's been taking lessons for about a year now, and the Yamaha YDP-145 seems to come up to me as a solid option. But before making a decision, I'd really appreciate some insights from people who've owned, serviced, or taught students on one.

I've read that Yamaha uses CFX samples with this model with its GHS action. It sounds good on paper for beginners, but I wonder if the action becomes limiting as students move into more demanding repertoire, especially with repeated notes and faster passages. I also want to know how GHS compares with Yamaha's higher-end actions - or even Roland's PHA series - from a teaching perspective. Does the difference matter to most students, or is it only at more advanced levels that it becomes important?

Also curious how the instrument holds up over time. Have any of you had any regular maintenance issues with the key action, pedals, or electronics after several years of regular home use? And generally, are owners happy with the sound of the piano over the long term?

I would love to hear your experiences.
