I finally got this set the other day. I haven't watched all 26 episodes, but the ones I have watched are just amazing. I can hardly believe that this series is now on DVD (well, 52 episodes so far, anyway). When I spoke to the late Peter Fernandez all those years ago he told me he was still trying to get the series back on the air. He always believed in the show, even though Speed Racer was much more well known and famous overall. I know it's redundant, but he was a great man.
So here's the case, which holds all three discs in it in a nice comfortable way. The Toho Icons of Sci-Fi set had their three discs in paper covers instead of this way. Lame. So score one for Marine Boy in that respect.
