I made the mistake of buying a 3D movie that wouldn't play for our 4 year old the other week (Christmas, we don't have a 3D TV)....Luckily, there was another Blu Ray disc in the box, but we had a wee bit of melt down before figuring that part out.
When I've been to friend's houses who do have them, I just don't get "Wowed" by the technology as compared to what you see in the theater with 3D.
That being said, my neighbor swears by his LG Electronics 47LA6200 47-Inch Cinema 3D 1080p 120Hz LED-LCD HDTV with Smart TV. I think he took about two days to get the hang of the "Smart TV" functions, but the set also comes with four pairs of 3D glasses. I do not know what the pain threshold is to buy new glasses if you lose/break them though.
