I can't really comment on the NTX 1200, but I briefly played one a few hours ago, and I chose to buy the NCX 900R instead. Playability of the NCX 900R is superb. I've yet to take it out of it's case, since I just got home a few minutes ago, but I'll give it a good workout tonight or tomorrow. My first impression though, is very positive.
I instantly took a liking to this guitar. (I wasn't even shopping for a guitar today,,,, I went to look at keyboards actually,,,, but once I had this thing in my hands, I wasn't about to procrastinate and "wait". I've missed too many great guitars because of that.
Here's a link, and you'll find a brief review there as well;
