Ready to cut n'paste:
VIDEO DAIKAIJU
PO BOX 185

Unfortunately, they have no site--they had an unofficial site with a catalog listing but it's since turned into Pop-Up Hell. They have pretty much everything, and the heavy hitters come subbed or dubbed. Ask for their catalog.
You can also investigate Showcase Collectibles, which DOES have a website (
http://www.godzillatoy.com) BUT my sole order with them to date is currently six months, three days, seven hours, fifty-two minutes and six seconds overdue...
What to compare? Get the one between the two you've already chosen. "Gojira no Gyakushuu"--AKA "Godzilla Raids Again," "Godzilla's Counterattack," and "Gigantis, The Fire Monster"--also suffered severe cut n'paste itself. If you can latch onto a copy, "Varan The Unbelievable" is a massacre of "Daikaiju Baran."
After that period, most kaiju flicks went for simple dubbing, rather than additional footage...however, you can still provoke giggles with the US poster for "Godzilla vs Megalon," (1976), which tried to tap into the "King Kong" remake hype by showing the title combatants squaring off atop the World Trade Center towers of New York, which of course never happens in the film.
