the recommended monitor refresh was 100hz or above even back then, so I really don't know for certain that any significant improvement has been made to the glasses in that respect, as we are only at 120hz for most flicker systems. Sure monitors have improved, but the glasses, really? I'm not convinced.

7 or 8 years ago, flicker glases went for under $25, all you needed was a relatively high refresh CRT and current gfx card like the geforce fx 5500. The glasses haven't really changed as far as I can work out, except in that the prices have been hyper inflated and there are claims that something is new. I'm not sure that an infrared strobe, a suitable sensor, a rechargeable battery and a couple of transistors warrant the extra $100+ .... oh right, fools and their money....of course... nevermind, nothing to read here, move along...
