Just my opinion, obviously, UGH !!!!! I mean, the piano sounds wonderful, but what in the h-e-double hockey sticks is Korg thinking with their designs lately. The Nautilus 61/73 is not only hideous, much bigger than need be and very difficult to pick us with the goofy rounded edges. The 88 looks fine/professional. And now this Grandstage X. Please, Korg, stop with cartoonish designs and bring back professional looking keyboards. Okay. That's my rant for today. Oh, I'm STILL waiting for Kronos 3, but not holding my breath.
