He already has a 2D projector and a screen.
I totally forgot about 3d glasses lol.
The only Sony one we can find here in canada is from the Sony Store. Whats you take on this one?
That's a good one, can you also get the Epson over there, you will get more brightness and better 3D from the Epson.
The absolute best 3D is from DLP tech, zero crosstalk, all other techs will have some even if viewers do not notice, for DLP and the price you mention i'd look for a high brightness one which uses RF, NOT DLP link, choices are limited with DLP, older models have less brightness, if you go DLP i'd go for the announced Optoma HD50 over a Benq W1070, reason being is it should have better black levels and now they are using an RGBRGB colour wheel it will be much more accurate with colours out of the box, faster colour wheel also means less chance of seeing rainbows, another consideration should you go DLP.
Whatever you get, my suggestion is to get it calibrated, 3D calibration makes all the difference, you can even do it yourself by buying an i1 Pro 3 meter with Calman or Chromapure, it's fun to calibrate but does take time at first when you are learning.
