Zalman rules! I bought a 22" from Amazon, pretty cheap for the quality... don't need any expensive 3D glasses (i've noticed that if u wanna buy another pair, is almost at the same price like the original kit). Even the ones from the cinema are working without any difference in quality. On one hand, u can get this one with 2 pairs of glasses, on the other hand, you'll have to buy a 120hz monitor, plus one pair of Nvidia 3Dvision... and the price difference? double.
Almost 300 euros for Zalman, 250+180(+150 if u want the second pair) for the second option
