Well my Optomas finally got here... and don't work very well at all. I shouldn't say that - the picture quality is great, the 3d blew me away... but the glasses won't stay sync'd with my TV. I was a little weary about DLP Link and now I'm reminded why. I used the glasses with the Avatar game and from what I've read, if they don't stay sync'd with Avatar, you'll have issues with most 3d content. If they stay sync'd for you I'm jealous but mine are on their way back. I have a HLT5687S which is an LED based DLP so I can't even blame an old bulb.
Looking at the other options out there for glasses, I think my next pair are going to be the x103s. I'm definitely going with IR based glasses and I like that the x103s wrap around to block light coming from the side.
Will post results whenever I get the x103s... I am choked.
