I've decided to put my KN7000 up for sale
I'm in Nottinghamshire UK
It is in good working condition and has a 1gb SD card plus the O1Expansion board. I thought about £500 would be about right.

Peter, What keyboard will you be using, John C.

Now that's very sad Peter

You should ask much more than £500 - the KN7000 is currently bringing between £800 and £1000 on UK eBay, without expansion boards......
