I purchase the Optoma hd66 a few week ago and I be very impressed with its performance . the projector size be compact with a quiet fan and picture quality be extremely good . set up be a breeze and the 720p image via HDMI be superb . I couple it with the Optoma 3D-XL adapter for 3d projection and be extremely pleased with the 3d output -lrb- although one do tend to lose some picture brightness -rrb- . I would describe the overall value at this price range as excellent . the ability to also project 3d -lrb- with the 3d-xl adapter -rrb- with great result make this a fantastic solution for 3d projection on a budget . fantastic projector !
