Have you considered the 400 disc CD/DVD Mega Changers like the Sony Sony DVP-CX777ES or SONY DVP-CX985V. I'm pretty happy with the 300 disc version but keep eyeing the above that play SACD. I loaded the dvd's into the high end numbers going down and the cd's in from one up so I add discs to either end depending on type. No cases or racks to deal with at all.
