I'm back in Canada now for the holidays, but I will be in Mexico again in January. There's limited stuff available where I have been staying. The big American stores like Wal-Mart and HEB seem to only carry Mexicanized versions of the American merchandise, but I'm planning a trip to the Plaza Sesamo theme park in Monterrey and will be in Mexico City as well so I will keep an eye out for stuff.
I'm really busy so no promises, but I will do my best if anyone is looking for anything specific.
BTW, if anyone is looking for something specific email me privately through the board because I usually only check the Puppetry section and rarely read this part of the forum.
