I just purchased this tv, and having it delivered on Saturday. Ive been reading non stop since this afternoon and I think I know less than when I started! I saw the starter kit for 400 bucks which seems insane. Do I really need this? I have a ps3, will it play in 3d, or do I need the adaptor? Please help so I know what I need when my tv comes. Also, saw several glasses on ebay, should I avoid these?
