Replacement for Jewel Cases?

PsychoBrat asks: "I'm surrounded by jewel cases at work and at home, and although most of them are still holding together to some extent, a lot of them have either cracked fronts, broken hinges or snapped teeth. Slim cases generally annoy me because I can't tell them apart by looking at their spines, and wallets take too long to sort through. What do you use in place of the standard fragile jewel cases to keep all your discs organized?"
