Somehow I broke the joystick on my Zen V/PLUS. So I searched for a fix and found nothing but an Instructable for disassembling it ( found here
). After taking it apart I cut a piece from the ink tube from an everyday 0.15¢ ink pen about 1/8", reamed it a bit with my pocket knife to enlarge the opening just a little so it'll fit snugly. Reassembled it, now I'm happy again!
