If you save as slowly as I do, you can kill two birds with one stone. By the time you have enough to buy one they price will have dropped. I am looking at a referbished 3D ready Viewsonic Projector. For about 1/4 the price you can get the same thing. The fault is in needing a room viod of most light to really enjoy it.
Seems like there is always something in the way of getting rich...
