The large size and price of the Z8000 may make some people question why they couldn’t achieve similar results with a much smaller and cheaper projector (like the previously reviewed Epson G5350). The difference is that the Z8000 is a commercial grade projector, which is designed to have superior sharpness, color, and video and image performance. While other lower-priced LCD commercial projectors have good color and image quality, none have the high contrast ratio and depth of image that makes Z8000 the choice for those needing superior picture quality for videos, photos, spreadsheets, etc.
The price of the Z8000 is actually rather reasonable when you start looking at high brightness WUXGA (basically 2K) projectors. Consider - Christie's HD6K, a 6500 lumen hi-res projector stickers at $59,995. Digital Projection's and projectiondesigns 3 chip dual lamp projectors will also cost a whole lot more.
About the only similar resolution projector (2048x1200, 1980x1200 or 1920x1080) I can think of, that costs about the same is Sanyo's PDG-DHT100L, single chip commercial DLP projector, which costs a thousand dollars, or so, additional, and is rated 500 lumens brighter. Sony's VPL-FH300L, their 6000 lumen hi-res, dual lamp projector stickers at $35,000. So, as you can see, the Epson Pro Z8000 is starting to look like a real bargain.
Also, being a dual lamp projector, it would still be usable while waiting for a replacement lamp if one lamp failed. The Z8000 would also be a good choice to use in multiple projector applications (like casino sports books) to show sports events, as well as in high end digital signage applications that demand the highest image quality. Other applications would be large nightclubs, auditoriums, lecture halls, museums, or for permanent, quality visual displays (such as digital signage) in a wide variety of venues. The wide range of optional lenses also allow for great flexibility in the type of installation, be it front or rear projection.
Bottom line, if you need the best possible picture quality for your application, the Epson Powerlite Pro Z8000WUNL has it and is packaged in a commercial-grade projector that should require minimal maintenance.
