it's my understanding that the kawai digital pianos have the best and most realistic action relative to a real acoustic grand, and the electronics are not too shabby neither, they're at thei middle and high end of the market so it seems like a solid choice, i think as long as you didn't get the absolute cheapest bottom of their offering they make you should be pleased (i don;t neccessarily think they're cheapest one will be junk just in general it's better not to come in at the bottom of amy manufactureres offerings since they tend to cut lots of corners for a price point to appeal to a lower market).
I just got one a few days before Christmas.. I really love it as a digital piano. I add that last part, because as great as the action is and nice as it sounds, I still can't treat it the same way I treat a real piano.. but the difference is small.You made a great choice in my opinion. I compared the Kawai with high end rolands and yamahas and I'm really quite lost as to why anyone would ever choose anything but the Kawai. The action is just so much closer to real as opposed to the empty action of the roland and yamahas.
