Hi! I must sell my Sony W400Q (tought times) so I am doing for $200 plus shipping. THe unit needs a blue polarizer which is $150 from Sony (they are in stock) and I can even install it for you if you want. Even as a back up or parts for another W400Q this is a good deal. Just consider if the prism goes dead in your current W400(hopefully still around) the replacement will be insanely expensive...think buying a new entry level DLP type of money! I am only selling it cause I really need the money. Regards S O L D !
