I have their strummed acoustic and although limited, it's easy to use and cheap. If the new one's like the one I have, you've got up- and down-strums for every major and minor chord assigned to 24 MIDI notes, with multiple velocity layers and round-robins. This new one apparently includes double-tracked strums as well.
 
$16.80.
 
Requires full Kontakt version 3.5 or higher.

Their audio demos didn't wow me.  Anybody who's bought this, please "chime" in and let us know how you think it sounds.
 
Cheers,

You're right, there's not a huge WOW factor there. You're not going to use it for a cover of Tambourine Man. I've got a few OK electric 12-string samples already, and they're not very versatile either. But I do use them, mostly to pan opposite another electric rhythm guitar for texture. It's just another tonal choice to have in the palette.
