Its got the built-in electronics, and I've played one, thought it sounded fantastic. One of the best acoustics I have tried, and I've played quite a few. It sounded better than my hand-made japanese acoustic which is worth about 3x more.
They say it sells for $999 but street price seems consistent at $699. Be warned, its made from composite materials, but that's not necessarily a bad thing, (look at Ovation) and the sound speaks for itself. Worth a look for sure.
Just as a side note, after about $600 or so you really start paying for the fancy smachy in-laid "mother of extinct weeping pearl" flying seagulls yada yada... may look nice, but has nothing to do with the sound of the guitar. I've tried some very expensive guitars that didn't sound nearly as good as others that were a third of the price.
