The best one I know of is the Taylor 514CE-N which is a nylon string acoustic guitar, with cutaway. It was hard to tell from the image I saw, but it may have electrics as well. Not sure what your budget is though, because this is a $2,800 (USA) priced instrument. Martin Guitars also make a nylon string acoustic with cutaway, but then you are talking close to $4,000. Plus I think the Martin has built in electronics as well. Other than these two, I don't recall an acoustic nylon with a cutaway design and no pickups.
