The Japan 100v unit DOES work in Europe, without any voltage transformer. I've just changed the plug with a compatible one (or you could use an adapter) and it worked. It does not overheats or anything else. I just wanted to confirm this, and thanks to the original poster who discovered this first.
Here are my impressions (see at the end for the bad and ugly):
The good:
-very, very good 3D, the best my eyes have seen.
I've seen Avatar at Imax, but the HMZ does 3D better, imo, much more natural looking. I've only tested it on my PC, some 3D movies and one game (also in 3D). I have Doom 3 BFG ed, which has 3D settings integrated in menus and i can not tell you how much impressed i was about the experience. The resolution seemed low (i'm not sure how Doom 3 BFG does side-by-side 3D, but it seemed it was lower than 1280x720 per eye), but oh man, the immersion it gave to that old game....Games benefit greatly from 3D, much more than movies. I cannot wait for Oculus Rift to appear on the market.
-the sound (with the default earbuds, because i didn't have time to test it with my full open headphones).
The included buds sound very good, clean and have bass. Sony did a great job with the sound virtualization, in both games and movies. I was not expecting to like it, but i did.
-plug and play
Pretty easy to set up and connect it to pc and PS3. Easy to button and menus are nice. When connected to my PC, windows found it as Sony HMZ and changed the resolution to 1280x720. Even if you have it at 1920x1080, the HMZ does the scaling to 720. But i've noticed a strange thing with my movie players (Splash Pro and PotPlayer), every time i switch to full screen, the screen goes black for 1-2 seconds and then it resumes; like it changes resolution or something. It's definitely a PC software issue, because if i turn off GPU video acceleration, all returns to normal.
-(low) resolution.
A plus because it didn't bother me in movies and games (though games need a little AA).
-no discernible input lag
I'm no pro player, but i know how input lags feels (i've returned a pc monitor and a wireless mouse because of this). I've played a little bit of fast paced Unreal Tournament 3 on it and didn't feel anything wrong.
-the image, when in focus, is clear and does appear big. Very good contrast, at least to my eyes. Cinema size or projector size big. Not sure how big, but i need to move my eyes from corner to corner, like i would when sitting a bit too close to a screen. You need to watch it in total darkness, because otherwise you lose half the effect and it just becomes a normal, tv like screen. So yes, it is big and cinema like....BUT:
The bad:
-tunnel vision. I finally understood what some were saying. Although the image appears BIG (in total darkness), you feel exactly like you're sitting at the cinema with scuba diving goggles. It's not because you feel something on your head or face, it's because the light from the screens is reflected on the black plastic around each lens, the deep plastic rim that's there to allow each lens to be adjusted left and right. I think this could be corrected somehow, but i'm not sure how easily. But i can say 99.9% sure it's not because of optics, they are fine (but of course they will reflect light from outside, if you don't use the blockers or don't watch it with the lights off). This tunnel effect you can ignore...or not. Depends on what you're expecting. I wouldn't say it breaks the immersion, but you must learn to deal with it and just focus on what's on screen.
The ugly:
-apparently i have a mutant large head, because i can't get it to stay in place. It just slides, under the weight, up front, onto my nose bridge. The lateral straps are at max and the forehead pad is at the lowest position (otherwise i can't put it on my head, not enough for my eyes to fully see the screens). The two straps at the back (including the elastic one) just keep sliding through my hair and can't keep the whole thing in place, until it rests on my nose, like some heavy glasses. And since it sits on my nose, my eyes are too close to the optics, resulting in smudges from humidity (i guess).

The thing is i can get a clear picture pretty easily, no optics adjustments needed, it just doesn't sits there for too long.
In conclusion, i'm not sure what i'll do, sell it or keep it and try to mod it. If it were cheaper, i would definitely keep it. But for now, if someone is from Europe and wants to buy it, leave me a PM and i'll think about it.
