Well, I’ve been gigging on a Studiologic NC2X for about two years now, and it’s been excellent, the occasional mid-gig pedal malfunction notwithstanding, but it does definitely feel more like a keyboard than a piano. If what you’re looking for is more along the lines of your Clavinovas or other attempts at that real piano feel, I mean, there’s a reason the Clavinova is the first name that comes to mind. In general, Yamaha, Roland, Korg, and Nord are the most widely recognized, but don’t discount Casio for a good deal, and I’ve got a personal soft spot for Studiologic, as I mentioned.
