The best 2d Large screen LED sets basically come with 3d already. I own full array local dimming led sets from Sony and sharp elite both of which have active 3 d.
Tougher decision if you have top end blue ray projector or tv set before 3 d was available.
In TVs however, the best 2k LED sets have 3d active already built in.
Most new titles are coming out in 3d, and buying thru amazon at 24 - 30$ is worth it for the 3d experimence at home.
The overall question is further complicated by 4k and OLED now hitting the market but that content will be extremely limited for several years.
