Hi No Tori has a few episodes of Shaider

Generation Kikaida has official release boxsets of Kikaider (duh), Kikaider 01 (also duh), and Inazuman.

Someone did a sub of the Mechanical Violater Hakaider movie (which is nowhere near as porn-y as the title might suggest, but it is still pretty cool). I have no idea if it was official or fansub.

I'm pretty sure that there's a full sub of Doguchan out there somewhere, too, for anyone who wants to combine tokusatsu with breast fetishism.

And I don't know if you want to include Ultra in here or not, but TVN has all of Ultraseven X and MCS has done a scrub of the kinda/sorta bootleg Ultraman set and all of Ultraman Tiga (which I think is also a bootleg scrub).

That's all I've got off the top of my head/quick site checking.
