The two reasons why they shut down production of the K1000 is that:
1.) Too few people willing to buy it (obviously)
2.) The machines that created...I forgot, the drivers? Something like that, it was rapidly deteriorating, and couple that with the first reason, and they cut production off.
Of course I think everybody would like another round of K1000, but the price won't be like back then (only $400 or so IIRC), it'll be like now; $800-$1000.
