Personally I don't think it's worth investing anything extra in. My tv came with it. Fios TV has some 3D movies if you subscribe to HBO (or starz too I think). You have to buy glasses too though, which costs extra unless yours comes bundled with some (in which case its just rolled up in the price anyways). There is one 3d sports channel, but nothing really that interesting on it. Image quality is ok, but nowhere as good as if you see it in a theater (at least on my set). Have to get a 3d bluray player too if you plan on watching those (which is extra vs. a non-3d player). At a minimum you are probably looking at an extra couple hundred in costs vs. non-3d stuff. Now that I've seen it, I'm perfectly fine if I never watch another home-3d movie on it.
