Summary: Personal Experience Okay, so I've had this projector for 2 years now and looking back at most of the reviews, I can see why you complain. Leveling the screen is kind of a problem... IF YOU AREN'T USING A FLAT SURFACE. As for rainbows and poor image quality you should look at your other equipment (DVD player, computer, VCR, etc.) first before bashing the projector.
Summary: On a "tight" budget for your home theater needs? That was me. I decided not to go above $1,500 between audio and video... well, that is a bit unrealistic if you also count cables and setup, but the Optoma EzPro 737 will get you one step closer to your goal. Here's why. It is by far the best bang for your buck, among the sub-$2,000 projectors.
Summary: Personal Experience Nice machine for the money. I've had it for two years and use it in the office conference room when clients come in and at home as a home theater on nights/weekends. Office application is great, bright, clear. Home theater is good, but not excellent. For the money it's a nice unit. Flawless reliability, easy to use. Problems Leveling mechanism is sub par. Need magazines or books to level display. Lens cap goes on and comes off poorly.
Summary: I just bought this thing from Amazon and all I can say is WOW!!!! This is probably the best purchase I have ever made. This thing is everything I ever expected and more!! It's very easy to use as well! I have bought other brands before, and this one just blows everything else out of the water! I have to say, everyone out there who is thinking of buying this, stop thinking. I bought it and I am extremely happy with it the moment I powered this thing on.
Summary: Personal Experience I found this projector to be just as bad as the Optoma EZ-750. But actually worst. The projector boast about a high contrast ratio. But I didn't notice it. I found myself comparing the EZ-750 side by side with the 737. I shouldn't have to do this with a projector boasting a 2000:1 ratio. The EZ 750 boast a 600:1 ratio. To be honest with you the Optoma 750 I had at the time was brighter and clearer.
Summary: Personal Experience I bought the Unit for 2900.00 Canadian in August 2003 and have had it running for awhile now and am therefore qualified to make a well rounded review. It is best fed by DVI/M1-DA from my Radeon 9800Pro in my HTPC for DVD's and ripped movies playing directly from my hardrive. As for my Bell EVU 6000 satellite reciever, I use component/M1-DA from my for HDTV/SD feeds. Composite and S-Video is absolutely attrocious!
Summary: Personal Experience I received my projector yesterday and had very high expectations that it would provide a better viewing experience than my Toshiba 51" rear-projection TV. Although I haven't had the unit for very long, it has been long enough that I know I won't be keeping it. The construction tolerances seem fine (except for the lens cap), but the "feel" of the unit is dissappointing considering the $2300 price. I expected MUCH better.
Summary: Personal Experience I was interested in the 737 and was a little scared at purchasing one from reading the online website/mag reviews. (The ones I'm sure you all have read as well) These review indicated things like "poor image quality", out of focus areas, etc. Let me say that I took the plung and purchased one of these projectors. "fingers crossed". Well I'm GLAD I DID. I turn on the system and started looking for these "problems".
Summary: Personal Experience i have had this projector for a few months now, in a dedicated HT room. projecting on to a da-lite high contrast da mat screen, amazing picture quality for the price, no pixels noted, and no rainbows! now that it is on an actual screen made for dlp. HDTV is unreral! Problems only gripe again, is no true DVI or component in, you have to run the component to USB/m1-a cable but it still works fine.
