The mini 9×9 goban (Cute Board? 10/31 EJ) has been tracked down. It’s available from Schaak en Go Winkel in 
Amsterdam, Scandinavia’s Mohsart (both offer 13×13 versions as well) and Jeu de Go.com in France. On the other hand, reader Dwight Anderson says the miniature goban “Would be easy to make. Just get someone to cut and plane a 2 x 10 board, draw the lines on with a permanent marker and finish with some varathane. You can buy the little legs at a local building supply.”
