Sorry, I didn't realize there are so many replies to this post
First: it's the complete system, the $465 kit (used a couple times) with one anti-newton glass.
Second: the beauty of Radeka's system is the carrier. You put that in the carrier position and you can remove and reinsert the inner carrier without worrying that the images will move. And of course he includes a book with a number of different masking techniques and chemical etc.
And yes, of course it's the photoshop that adopts some of the techniques, my title not withstanding
Finally, I have a tentative offer. I will update this post when appropriate.
// EDIT: Oh, this is the 4x5 kit, not the 8x10 kit.
