I thought you could get them at Marken also, which is similar
Might have that here too. Regardless, this is a place (very touristy) worth seeing and is on a nice "loop" (Durgerdam, Marken, Zaanse Schans, Monikadam, Volendam etc.) That is an easy day trip (unfortunately) by automobile from Amsterdam. You can see some of what these places are like on the following links: http://www.europebyphoto.com/holland-tour.html, http://www.europebyphoto.com/marken-tour.html
