My question is about the DLP. I'm one of the unlucky people who saw trailing rainbows on the early generation rear projection DLP TVs (I have no experience with newer ones). Will this be an issue for me on this projector, or has DLP technology improved?
well, ive never had a dlp and i can see rainbows with my w1070, in some music concerts, like adele or star wars movies (with the subtitles) but at least i can stand them, no headaches for now...

Definitely don't judge DLP performance based on early Rear-Projection units: these had color wheels that generally used to operate at around 1x speed; and RBE is why I wrote them off back then as well (I'm also very sensitive).
But things have changed a lot in the 5-10 years since RP has fallen out of favor: even today's lowest-end DLP projectors tend to have 2x color wheels; which decrease the likelihood of visible rainbow artifacts.
The W1070 takes this even further and has one of the fastest wheels on the market, taking it all the way up to 6x speed.
That's a serious improvement; and sufficient such that (when the wheel is running at full-speed), I practically don't notice rainbows at all.
(Side-note: There's one catch, though - in that the input framerate affects effective wheel speed. So a bluray running at native 24fps actually yields the W1070's slowest wheel speed - still above 2x, but below the maximum 6x. Broadcast HDTV at 60fps is much faster; and 50fps - used for European broadcasts - yields yet-faster full speed. This also explains why many will witness RBE when watching a bluray but not (or less so) when viewing a broadcast. Many bluray players offer the ability in their video settings to output at 60fps - if this is offered by your player and you're RBE sensitive, set it to do so. It's normally called something like 'Video Output at 24p' or the like; which you'd set to 'Disabled'. Using 50hz with my HTPC's, I see practically no more rainbows at all - even with white-on-black subtitles).
For this reason, I'd recommend you at least audition the projector before writing it off completely: you may be pleasantly surprised. See if you can arrange a viewing at your nearest AV store.
If it still doesn't work out, your only real other option in this price range is 3LCD technology; with Epson's 2030 probably being the best bet. It loses out significantly on contrast ratio, sharpness, and input lag; but it's also free of rainbows to everyone and has slightly better blacks. It does, however, offer a full 2-year warranty (compared to the 1-year offered by most of the competition; including the W1070).
