sharp z9000 dlp feed back?

any sharp z9000 owners could give feed back i have heard of problems with this unit and sharp was going to stop selling it?
My sharp works great and have 400 hours of use with no problems. Check out avs forum for more on the sharp. It is a winner!
I had 2 units that both had a mirror get "stuck" on them....... picture was great.... but 2 new units with the same problem sent me looking at the Marantz.......will wait, however, until my new theater room is completed and hopefully by then the HD2 pj's will be cheaper.
