I got my PX-350 3 weeks ago, here in Seoul for about USD 900 with cabinet and pedals. So far I am delighted with the quality. I was coming from a Casio WK-1200, which I really liked, but now I don't want to go back to it. A very different quality level... One thing I miss in my old keyboard is the design of the buttons and clear labeling of all the functions, instruments etc. And the nice graphic LCD display, which makes the LCD in the PX-350 look more like a pocket calculator. Of course it would not look very good to have an electronic "piano" with what looks like an airliner cockpit behind it. On the other hand, there are already enough buttons to destroy any clean "piano" look, and yet they are not enough for good ergonomic control, with the 2-line display and the 1-button-27-functions approach. I suppose the future will be in a tablet-like touchscreen with virtual buttons and messages, which can reconcile a clean design with ergonomics. One question for other Casio owners: I have tried to install the Caiso IDES 4.0 software, which could make it easier to manage user presets etc. than through the PX-350 spartan controls. But I ran into an install problem in Win 7 64 bits. Has anyone tried it? I am not sure it is compatible with Win 7, or even with the PX-350. The Casio site is very economic with information on IDES, it looks they have quietly abandoned it. On the other hand, it is mentioned in the PX-350 manual...
