Hi,The old Bs 3 cannot be upgraded to the Newer 3D spec's to costley so have to get new 3d box.
As for projectors,Sony can suffer from crosstalk,slow refresh rate on the glasses.
I have a Jvc HD 1 Projector (non3d) but the new Jvc 3D JVC DLA-X3 pj are on the 2nd jen which have great reviews.
Also check out the new Panasonic 3D pj,PT-AT5000 fab pic no crosstalk 480hz glasses.
And Optoma HD33 1080p for cost!
Bv7-55 & Bv7-32...Blue,lab1's x4,Yes4Blue, 6000x4Blue,Beocom6000 Blue,Beo5.Oh what a Blue set-up & a Beosound 5...After all,its Bang&Olufsen!
