I bought the Koskin 20-Disc CD Hanger from Meritline for $2 today. I've got a handful of wedding-related CDs and DVDs taking up room in the apartment, like our wedding video (thanks again Stuart & Brian) and wedding photo backups. Since I have a small file cabinet, this will minimize the room they'll take up.
I'd like it better if the CDs were protected from dust a bit more, though. But, $2!
