Hi Don
Thanx for your report verifying what I heard.  I wondered if I had gone daft.haha  I've never cared for Casio keyboards, no offense meant, just a personal preferance.  But, this little sucker is surprising for what it is.  Not every sound on it was terrific and by a long shot at that, but, they must have a development person or team that like to make sure the keyboard/combo type instruments sound decent.  As I mentioned earlier I liked the piano, vibes were exceptional compared to what I've heard on all other makes, there is a Rhodes type sound that I really liked.  There was an organ sound or 2 that was decent.  The accordian sounded like crap, there might have been some usable guitars, but I didn't spend much time with voices other than what I mentioned.  I actually think the piano sounds better than the other and more expensive Casio's sitting there.  
If that thing still sounds good through my Eon's, I will be extremely tempted to get it.
The keyfeel, was I guess what you'd call semi-weighted.  A rather light touch.  For me having more of an organ background it feels real good.  For a piano player, it would be an individual thing.  Definitly much better than the NP-30 though in all ways, and for $100 less. 
My bet is there will be more people on this forum with one of these than you'd normally expect.
Yes, Ian, I agree, if they stuck in just a little more quality sounds, they'd have a big winner.  However, Casio isn't dumb, they know the money to be made is in what they make not for the "pro" market if we can call it that.
In a nutshell, just a major surprise.
