thedalek: I'm toying with the idea of making my own hard paper box to put the keep-cases in, like the one in the official Indiana Jones set. Should be possible... If it's not though, I might do one for a quad keep-case instead.
BTW, I agree on the official DVD covers, they're awful. Looks like they're made by some kid who's just learning Photoshop having a field-day - with the glows and the lens-flares etc.
