cheaper than US$10 gosets

I am looking for cheaper than $US10 go sets to sell to beginners who
expressed interest in the game, the cheaper the better. A lot of
newstarts in go lost interest because they cannot get other beginners
interested in playing on home made sets (ugly), and cannot find
players on the net for some reason (no access to internet being one).


I hear some places one can get sets made of cardboard very cheaply but
I need
a contact source. I am also looking for something that is
lightweighted and 9x9 sets would do fine.

Thanks for help
