Let us know how the quality is. I know it claims to have been restored but on the same page it also warns that the original elements were in bad shape so it may not look that great. Even though I've spent a great deal on getting almost the full series (just missing one story), I would probably double dip if it was cleaned up remarkably more than the previous releases.
Actually what I might do is if they also restored the Toei movies, I'd buy those for sure.
And yes, it's one of my favorite shows too. Being very into early pulp, cliffhanger serials and toku in general, it hits all the marks for me. It's like if The Shadow was a Kamen Rider fighting villains from a Jiro Kuwata manga. Great music too. I'm wondering if it's original scores or lifted from American serials, because some of it sounds super familiar.
Speaking of music, that was popular in the early 70s.
