I got some pairs of generic active glasses that were every bit as good or better than the active glasses that came with my plasma TV. And those generic glasses were rechargeable whereas my "official glasses" had to have the battery disc replaced fairly regularly (if you watched a lot of 3D as I did when I first got the TV).
If you're talking about active glasses, have you gone to Ebay and searched for rechargeable 3D glasses?
