I got this as part of a P/X deal with my local keyboard store. I can't put a firm price on it, though I'd suggest you pay no more than about 150 dollars. It is the only one I've ever seen, so if anyone else out there owns one, please feel free to get in touch!
Comments About the Sounds:
Basically, this has the choir sounds that everyone seems to like the K1 for. It's a good filler when used with other keyboards and the strings are quite pleasant and not too tinny
