Help me selecting a projector for my HT


The budget is $5500 and I need a DLP/LCD projector (and screen soon afterwards) new/used to show on a 100-120" screen size. It will be used primarily for movies with DVD's as the source. From what it looks like to me, a used/demo DLP from Sony/Runco seems to be the best way to go. What should I do?

I have the Sanyo PLV60HT, 106" Dalite screen (0.8 gain) and ceiling mount--all together was $5000. The Sanyo 60 has since been replaced by the Sanyo 70. The Sanyo 60 can now be had for $3100, and the 70 for $5400. they are 16:9 native panel LCD. I have nothing but praise for the picture quality and reliability of my projector.
Have anyone of you seen the HT1000 NEC unit? The Sanyo sounds interesting, what else did you look at?
Well, at the time my choices were limited. My primary criteria was a native 16:9 projector, which ruled out all the CRTs. My choices at the time were the Sony 11 and Sanyo 60. The sharp 9000 hit the market just after I purchased.
