I have the 9000 on order. The factors in my choosing it over the D-ILA (which I prefer on general technical merit) were:
1) Noise. I don't have the "in another room" option you had, so I would have had to purchase a hush box -- that would be extra expense and hassle.
2) Need for calibration. I didn't want to go to the hassle. However, since the one you have a line on is already calibrated, this sounds like a non-issue.
3) Lamp cost. The D-ILA lamps are stupendously expensive. The DLP lamps are expensive as well, but are longer-lived and cheaper than the D-ILA. I think that it worked out to approximately half the per-hour lamp cost with the 9000.
4) Need for an external scaler. I *think* that most people use an HTPC or an external scaler like the TAW Rock or Faroudja NRS with the JVC. The Sharp has quite a good internal scaler, so for DVD's you can get by without this expense. I may purchase a Faroudja because of its reputation at making broadcast and satellite NTSC watchable on big screens, but I'm going to try the Sharp and also the DVDO (which I have lying around) first. In any event, the NRS for the D-ILA is about $1k more expensive than the ones for all other resolutions, so this is again a cost factor.
5) Contrast ratio. I don't think that the D-ILA, even calibrated, matches the 1100:1 contrast of the Sharp. They do look very good, especially on a GrayHawk-type screen, though. If you can use a gray screen and have perfect light control, this is probably not an issue.
On the positives for the JVC: the complete lack of rainbow, the excellent fill factor and the total lack of any moving parts (except the fan).
It's a pity you can't see the Sharp and the JVC in person. I was fortunate enough to be able to audition both. I liked them both quite a lot, and decided that the no-hassle nature of the Sharp plus its perfect throw-distance match to my room made it the winner. However, my next projector is more likely to be a D-ILA or other LCOS technology, just because I think it's the technically more elegant solution. I just didn't find any that were plug-and-play to the extent that the Sharp is.
