I have the 65VT50 and Im using 3D glasses from Dimensional Optics and they work great. I order on a Monday and had them by Wed. There website is http://www.dimensionaloptics.com
We've had out 55" GT30 Panny for almost a year now. I decided to get some 3D Glasses at the same time but really didn't have much to go on. I spent a great deal just reading users reviews all over....Amazon, here, Crutchfield, Best Buy....wherever I could find something. I wanted the offical panasonic models but at the time the price on them was close to $80+ each. Another name I kept seeing positive reviews on were the True Depth 3D ones. I was actually sold on them when I saw the 3D Active by Dimensional Optics. There really wasn't much on them in the plasma crowd but DLP users really gave them thumbs up. I also liked they were rechargable, came with a nice case, cloth and cord. The big thing was users liked the way they felt and are very lite. I do adjust/bump up the settings to offset the tinted lens but that's just something all 3D glasses have. They kind of remind me of the older Ray Bans Wayfarer sunglasses except with a bigger side.
