Shadowbox, I need one, where should i get it?

Hello,
So i am working on my PowerBook Picture Frame, and I need something to hold all of the guts, and I need a shadowbox so I can mount the PowerBook screen/motherboard in, anyone know where I should get one? They seem expensive, just wondering if someone is into crafts and knows where I could get a good deal.


Thanks,
Tanner.

Hobby Lobby has great shadow boxes.

I bought a few from Michaels arts and craft store this past week, to house some of my Wicked collection in... they had them for 50% off...
