i dont see the issue with used glasses personally if you buy a used new tv to save a ton of money why not glasses long as they are in perfect condition you can always give them a good cleaning haaaa. but they are not expensive like they were last year im happy with my two free pair i got and have not realy needed anymore. i dont watch 3d all the time either i have over 35+ 3d movies and have only watched like 5 of them. i love 3d for sure but not a everyday thing and as anything in life you have to be in the mood. im more concerened with getting the tv on the wall theater system setup etc next up led lights
