Right On man!
It sounds good... I'd like to see it when you get another camera(I'm kinda in the same boat, but I never had a digital camera and I dont have a scanner to post pics with), I'd like to see how your box turns out with the plexi-glass,
just remember if you use a sliding-door setup make sure you use a clasp or lock or something to hold the plexi in place, I'v built boxes witht the same sliding-door tecniuqe and when I turned in the direction the door opens it had the tendancy to slid open, maby the workmanship was bad or something!
