Sorry, haven't checked the list in a while. My source for the photoresist was http://www.digole.com/index.php?productID=228

The web store appears to be Canadian but the products come from China, so shipping can be anywhere from a week to a month.

It's a negative photoresist, so you need to invert the output of EagleCAD. I use Arm & Hammer Super Washing Soda as the developer (1/2tsp per 1C of water). I also use this resist as the solder mask, which works quite well.
