I just won a K2 in an online auction, $10 + $11 shipping and handling, so now I will be able to support a K2 properly. The auction site claims it has a good screen, but no power supply. The problem with eink is even a broken screen looks good until you try to redraw it. I hope it is a good screen like they claim (assuming it was never powered up).
I guess I can now find out "first hand" if a K2 really IS a "small screen DX".
