i bought this unit off of ebay a two months ago it works great, going with a 3D projector instead. Lamp has under 20 hours on it.
The previous owner had this unit sent back to JVC and checked out. A New bulb was inserted and any parts that were borderline were replaced by JVC's Techs in CA. Unit has around 620 hours TOTAL on it (Bulb has 20 hours on it).
I will also include a mounting bracket which generally sells for $150+ on Ebay
