I suspect you'll only find upscales if anything. :/
The sources I've currently settled on - Italian DVD for video and Japanese audio, patched with Polish DVD for two cards that were painted out on the Italian DVD (the Polish DVD is relatively poorly mastered, where the Italian one is mastered quite well) - are my current best known.
I'm not aware of anything other than YT uploads for at least some of the stuff (like the Goldwyn dub). The "Media" dub we have a DVD conversion a friend did for us that is probably as good as can be expected for coming from a low-budget VHS release. We've got a third DVD release on the way (from Germany) and will be checking that out.
The Portuguese DVD is apparently out of print and holy hell to find and the "stats" leave us with a lot of questions.
