Has anyone tried some of the alternative RealD compatible glasses for 3D movies at the Cinema?

There seems to quite a range around now. Although fairly pricey from what I've seen.

I'm not sold on 3D movies, but wonder how big a part of that is the uncomfortable standard RealD glasses!

Avatar I found very involving in 3D. Prometheus had impressive 3D in places, but I wasn't nearly as involved - could just be the fairly average storyline... But I was easily distracted adjusting glasses and by the light coming in around the frames of the glasses... would comfortable wraparound glasses be more immersive..?

I've seen a couple of other 3D movies, and either the 3D was gimmicky or plain sucked. But where it's well conceived it'd be nice to get the best of it, comfortably!
