It is a shame that new TVs don't have 3D, such as the Samsung QLEDs. But 4K projectors do- I've had good 3D experiences with the Sony 4K projector, and recently bought the Optoma laser 4K projector that has just come out... and has 3D! It's very bright and sharp focus, though I haven't tried 3D yet (which says it all, I guess).
I've bought a lot of 3D blurays from Amazon UK- as has been said, it's a good source of the 3D spice.
