I see there are at least a couple of Finnish people that are interested in getting their 3D anaglyph glasses. I'd like to share what I know to help you guys out.
I've currently found two places where you can buy 3D anaglyph glasses in Finland.

I have bought two of these. Fairly reasonable price per glasses if you buy two at once (about 3 euros/one pair), but if you buy only one pair you will be paying over 5,50€ for a piece of cardboard with colored plastic.

(unless you get a good deal from them - they are quite friendly over the email and responsive. It's always worth asking.)
These WILL work with iz3d drivers, and note that the anaglyph driver in iz3d is FREE (no 30 day limit or anything, only the other supported non-native drivers are 30-day evaluations - except ATI card owners with DLP systems I think). There's some ghosting that you get used to or not, but I'm not sure if it's the red-cyan filters from these 3d glasses or the inherent problem with anaglyphs - there's bound to be some ghosting ALWAYS. Our brain is quite good at learning to filter them out though.

I have no experience of these. I was thinking about buying one pair, but decided against it. There's no clear indication of what the color filter's are (left is red though, which it should be, even though with cardboard glasses it's quite easy to just swap the earpieces around to change filters on eyes), and with closer examination you can't really make out for certain from the picture are the glasses red-cyan or red-blue. These could be okay, but I wasn't going to risk it. And, well, you could always ask them are they red-cyan or red-blue before ordering.
If you have to choose between red-cyan and red-blue, ALWAYS take red-cyan. No specific evidence right now, but I'm sure there's a good reason which I've learned the hard way, just can't remember it now.
And I have to say, the only reason I joined the forum was for this thread. I hope my two cents worth are worth those two cents.
Have fun in the world of real 3D! (and BTW, I've recently been acquainted with M&B, it seems awesome although I don't have that much time to play it right now...)
