I purchased another discontinued case that DNJ recommended - it is plywood reinforced and the best case I have ever owned. Sure wish they still made them.

Gary, that by any chance would be the Guardian case is it? I purchased 2 about 6 or 7 years ago first a 61 key model for my old PSR 3000, then when I went to the Korg Pa2x purchased their 76 model. Both are still in good shape too. I believe Donny recommended Guardian to me.
Not even sure they make them anymore but here's a link to their web site
