I would also highly recommmend Art's reviews:http://www.projectorreviews.com/info...8602/index.php
He isn't perfect, just like all of us he has some BIAS's. What I find interesting though, is he favors the Infocus sp8602 over most other projectors even for black levels!
He pretty much says the infocus is an exceedingly well balanced, yet VERY VERY bright projector with some of the best skin tones ever.
Like I said, his reviews aren't all perfect, but it's impossible to be a perfect projector reviewer. God knows I made too many mistakes in my initial reviews and comparisons, but I learned my lesson that it takes a bit of eye training to truely see what you think you are seeing. The projectors these days are just that close at times.
Either the JVC or Infocus will work on a 120" screen, but with any ambient light or backwash light (reflective surfaces), the Infocus will look better. You are right, it is a light cannon.
A lot of us argue about different projectors, some of us even insult a projector on occassion, but most of us just hit a sour note a few times because of a particular issue we ran into.
At times all of us have probaly gone back and forth trying to decide a BEST projector, because most of these projectors all produce such fabulous images that the differences are somewhat minimal to any untrained eye, that's why we can't always give a clear choice to people.
I actually had some QC problems on almost all the different projectors I tried, that's why I have owned so many different projectors. I guess after owning a few, I just decided why stop now, mise well see a few more.
If you get a broken projector on your first purhcase, don't be like me and gripe about the brand name though, they all have QC issues it appears. Even the Mits hc4000 I had was broken (figures), checkerboard of death.
Just do a return or an RMA and don't look back once you get a replacement. Generally most projectors work fine after they are RMA'd, even if you have problems on the first unit.
One advantage to DLP is you don't get convergence issues.
Again though, black levels vs. DLP POP, well it's such a hard choice, that no-one can tell you what you prefer, only you will know that in the end. That said, the infocus sp8602 does pretty darn good black levels.
