I have one set of these for sale.
I'm the 2nd person to own this (got it from a trade with a fellow Geekhacker from Israel with my HHKB Pro2) and it's still pristine.
I believe the warranty still applies (bought around June last year?) but I am highly skeptical if this thing will ever break down unless it was bluntly hit by another of its own brethren.
Can't get used to the trackball, guess I will have to use a mouse and develop RSI but hey, I'm still young so I guess I can take it.. until then, this has to go.
Please PM me with your offers but I hope to let this go around the Asia region as I am from South East Asia. On a side note, I do accept trades as well.
PS: It comes with an extra snazzy red '3' ball
Some pictures:
This is the more accurate/real life colour of the red '3' ball.
Something's off with the WB and it appears orangish here[/spoiler]
