As jamman stated the Korg may be your better choice. Again this falls to personal taste as well. The N364 is pretty dated now. Be careful if you do get one though. Korg has sold a crap load of N364's and N264's over the years. These boards were used for gigging and worked well for it. I've seen so many for sale on the web that have their battle scars from years of road use.

Another thing is if you find one, ask about how much use it really has been put through. The N series have a backlit screen, but there are problems with the backlights getting dimmer over the years.

As far as specs, you'll get 16 tracks for recording, decent voice editing, a joystick for pitch and modulation control, floppy disk, good key action, and solid construction. The sounds are subjective. The Casio may have an edge on some of the acoustic sounds, but the Korg will take the cake in the synth department. As far as the acoustic piano is concerned on the N series, all I have to say is it sounds like a Korg. Some people like Korgs pianos and some don't.

Also the navigation may throw you off a bit in the beginning. The N series has a small screen, and you'll scroll through multiple pages for some functions.
