Add me to the list of proud owner of HD1000U as it came today via UPS in a clearly labeled Mits HD1000 box--thankfully not stolen by UPS or my neighbor. Mits (package was drop-shipped straight from Mits) should double box it to hide the content and improve durability of shipping. It's supposed to be my Xmas present but while my wife was away, I cranked it up to make sure the PJ is perfect so that I can 1) send in the rebate for the bulb (once my invoice get here from Spinitar in few days as the PJ was dropped shipped directly from Mits), 2) take advantage of the 72h return policy of Spinitar without restocking fee--luckily mine is perfect so no need for return.
What I found out about HD1000U compared to my trusty 3-y/o, modded (clear segment opacification and Hoya FL-D photographic filter in a DIY hushbox) is that it's a substantial upgrade. This is because of 1) 1280X720 native--no more black bars on 16:9 movies, 2) very quiet even in bright mode compared to LT150--on low lamp mode I have to lean near it to see if it's even on, 3) HDMI (works great with my HTPC using Radeon 8500 and Monoprice DVI->HDMI cable at 1280X720X60Hz and Zenith DVB612 at 1080i), 4) dedicated component input along with VGA which also accepts component if using VGA->3RCA breakout cable which means no more switching video at receiver level, 5) front exhaust means very difficult to put in hushbox--no need as PJ is very quiet (it's fan is quieter than my MDF-hush-boxed LT150 using a single Panaflo 80 mm fan), 6) much larger PJ lens make mounting my 62 mm Hoya filter easier (lens itself has no thread so must use insulation foam strip to wedge it into the lens socket of HD1000u), 7) 16:9 anamorphic squeeze is available even on VGA input (LT150 does not have this)--moot point since the PJ is already 16:9 mode but cool nevertheless, 8) less RainBowEffect (4X color wheel speed vs. 2X color wheel speed--I don't see any with LT150 anyways), 9) nicer remote (backlit orange compared to nonbacklit, credit card/chicklet style of LT150 (must use universal learning remote) with much greater range (bounce off screen easily where as the LT150's remote must be pointed straight at the IR sensor to work), 10) much brighter means better image, allows more ambient light, and better dark details, 11) better contrast means better dark details), 12) better scaling (480i via component looks almost as good as HDMI 720p/1080i). so SDTV is great (LT150's scaler is horrible--needs HTPC/upconverting DVD players/external scaler), 13) better colors out of box means easier to tweak for newbies, 14) better grayscale out of box means easier to use for newbies, 15) longer rated bulb life (2000/3000h vs. 1000h of LT150, so they claim but as we all know this is a toss up) for slightly cheaper bulb (LT150 bulb is usually over $300 and HD1000U bulb can be found easily for $300), 16) Offset is steeper than LT150--had to drop the PJ on a table mount a few inches to match the 16:9 screen being used for LT150, 17) Video Spectra at 1.5 gain works well for HD1000U also, 18) Zoom lens makes installation a lot easier to fit the screen, 19) DC2 means smaller gaps between the pixel/mirror and less SDE (mostly because of higher resolution than XGA), 20) no dead pixel (my LT150 had a peripheral stuck open mirror--luckily near the edge which can be hidden with screen masking).
On the other hand, modded LT150 has darker blacks (due to lower lumen output)--contrast is not as good though so dark detail suffers on LT150, and syncs to sources much faster than HD1000u. LT150 is of course smaller and lighter (3# and tiny). LT150's durability is proven for me (3 years modded without issues). It will be my backup PJ (bulb life is less than 100 hours left).
Overall, I'm very happy with the Mits so far. I had to box it up after a couple of hours until Xmas
