InFocus LD350 DLP Projector vs. Hitachi CP-S235 LCD

After buying a Hitachi CP-S235 LCD Projector, I decided it was time to compare it against a DLP type Projector. So my first choice was to purchase the InFocus LP350 which has both VGA and DVI computer connections, along with the standard SVideo and AV links.
The obvious difference between the two, is that the Hitachi uses 3 separate LCD displays (one for each colour; Red, Green & Blue) which act like light gates, preventing or allowing the light to pass through their pixels. The three separate images are then combined together to form a full colour image. The InFocus, on the other hand, uses a single DLP chip which consists of many tiny mirrored like structures that rotate, therefore, allowing the light to be either reflected towards or away from the output lens. In order to produce colour, a DLP projector has a rotating colour wheel which allows the light reflected off the DLP to be either Red, Green, Blue or White; the wheel cycles through these colours at a high enough speed for our eyes to merge the images into a full colour image. However, later DLP projectors have started to use a 3 chip design similar to LCD types, thus preventing an image illusion known as the Rainbow effect, whereby bright fast-moving objects have a multi coloured appearance (or Rainbow look) which is caused by the objects moving at a rate close to the rotation of the colour wheel; Unfortunately, the Infocus does suffer from this condition.
Anyway, enough of the technical side; both projectors were considered to display clear detailed images, however the Hitachi did seem to produce more vibrant colours than the Infocus. This was most noticeable whilst using the projectors for gaming. For standard television though, this wasn't as noticeable unless you watch those holiday advertising channels where the blue sea and yellow sand are far more vibrant than in real life.
Another noticeable difference was the size of the projected image from the two projectors. The Infocus' image at full zoom was a similar size to that of the Hitachi's at the lowest setting. Although this won't bother most people, for those of you who have a small room, and therefore, require the projector close to the screen, this could pose a problem.
Finally, the image of the LCD projector (Hitachi) had a very noticeable pixelated look to it (which is common amongst any LCD Projector), compared to very smooth, yet detailed image from the DLP projector. This is due to the DLP chip's pixels being far more compacted than those of a LCD, making it far better for television and video viewing.
So overall, both projectors displayed very clear detailed images, and provided enough light for viewing in rooms where complete blocking of light cannot be acheived.
The Infocus provided far smoother images, and also happened to have a far quieter cooling system compared to the Hitachi when running at full brightness.
The Hitachi provided more vubrant colours and allowed image sizes beyond that of the InFocus. In addition, the Hitachi provided the feature (not mentioned above) of running in a lower power mode (known as Whisper Mode) which extended the lamp life to 4000 from 2000, whilst also reducing the fan noise.
