En værdig kandidat imod X1 er Sanyo Z1 Her er et et uddrag fra en artikel om Z1 fra http://www.projectorcentral.com/sanyo_plv_z1.htm
PLV-Z1 vs. InFocus X1
These are the two mini-Titans of the economy class projector world at the moment. So we've been flooded with emails asking for recommendations/comparisons of the PLV-Z1 vs. the InFocus X1. Which is better? The answer is, as is often the case, neither. They are both great machines for the money. It is your personal preferences that will determine which is the best for you.
The PLV-Z1 produces a brighter, bolder image with more intensely saturated color. Some people like the boldness of the LCD image. Others prefer what they would describe as a more refined and understated image that you get from DLP in general and the X1 in particular. This is a matter of personal taste, and we cannot say one is better than the other.
The PLV-Z1 renders better overall HDTV quality. It is superior in sharpness, detail, and overall depth than the X1. If you plan a lot of HDTV usage, the PLV-Z1 is the better solution. However, for non-HDTV film and video, the X1 delivers a smoother, more film-like image. Pixelation is more apparent on the PLV-Z1 unless you take the steps noted above to mitigate it.
Contrast would appear to be a big difference between these two products. The PLV-Z1 is rated at 800:1, and the X1 at 2000:1. In reality, the perceived difference in contrast is relatively subtle. Due to the brightness of the PLV-Z1's image, if these two were staged side by side we'd find many folks selecting the PLV-Z1 as the one which was "higher in contrast." Our recommendation here would be to ignore the published specs on contrast. They radically distort the actual perceived contrast differences between these two products.
In normal operating mode, fan noise is just a bit louder on the PLV-Z1 than the X1. However the difference is not dramatic and should not be a big deciding factor between the two.
If you are one of the unfortunate folks who are sensitive to DLP rainbow artifacts, you may see them on the X1 and you won't on the PLV-Z1. That is because LCD technology does not operate with a sequential color wheel, so it cannot produce the effect.
The X1 has a 3000-hour lamp. We would suppose the PLV-Z1's lamp is no greater than 2000 hours, but that spec is not published by Sanyo. So those who expect to put a lot of hours on their projector should runs the numbers and do a "cost of ownership" calculation that factors in the cost of replacement lamps (ask your dealer for this info.)
