I'd sooner make a suitcase out of that overgrown iguana...
I recommend FINAL WARS (though I haven't seen it, but it rocks) (But I hate the way they treat ZILLA)
Eh. I dunno. What version of the movie were you watching? I only saw a couple monster battles, most of which were copout energy-blast battles and nothing of any real substance. I dunno though, I just expected more from a Kitamura Godzilla movie (don't know why). Maybe the fact that it was supposed to be a big final anniversary salute thing and was kinda lackluster just got to me.
The Millenium series is all good, pretty much, although all for different reasons. (That's Godzilla 2000-Godzilla Final Wars)
Godzilla vs King Kong and Godzilla vs Megalon are great, goofy, so-bad-they're-good examples of seventies stuff.
The original, of course, is where you should start, and get the DVD version called "Gojira" that came out recently, which has the original Japanese version.
Take a careful look at what's in them. Some of them are good, some of them include "shudder" the American Godzilla.
