Cost: Low: Free if you're family is asian, or if having 30 sets of chopsticks lying around is your kind of thing
Time: Low: 10-15 minutes
High: 25 minutes
Go to your local asian store or Chinatown, shouldn't be too expensive. Mine cost me a less than dollar fifty(9rmb). But I'm living in China now, so pretty its cheap. 10 sets of chopsticks for 3rmb.
