That's not a bad target price for a Collector's Edition of anything nowadays.. ;-)
I'm actually not worried about there being a floppy (I realize getting a hold of and dealing with floppies might be a hassle nowadays), as I have a bunch and can make my own copies.
A floppy label (printed and included would be a nice touch I think, even for people not wanting to put it on a floppy, but even a printable "official" one), manual and box would be great..
And I've seen some homebrew guys do boxes where they ship them flat and the users fold them into the box form themselves. Makes shipping much easier / less expensive.
Problem I see with that is that those homebrew boxes seem to usually cost a lot of money, just for the box.
I suppose it's all about quantity at that stage..
