Home Theater Projector Buyer's Guide
What will it Cost?
Cost is always a key factor in shopping for projectors. Here are some general price guidelines for home theater projectors in today's market:
$1000 or less: Even under $1000, there are some truly amazing home theater projectors available. The least expensive ones are the 1280x720 models (also known as 720p). They display DVD and Blu-Ray extremely well, and some cost as little as $700. However, there are some 1920x1080 (or 1080p) models that have dropped below $1,000 as well. This creates an interesting situation, since there are 720p and 1080p projectors at the same price point. Generally speaking, the 720p projectors will have more features and (likely) higher contrast, while the 1080p projectors will have the benefit of higher resolution, but are likely lacking in extra features and placement flexibility. Which one you choose is a question of what's more important to you, features or raw resolution.
$1000-$4000: If you have anywhere from $1000 to $4000 to spend, you are in the price bracket dominated by 1080p projectors. Many of the most popular projectors on Projector Central fall into this price bracket, including highly flexible 1080p LCD projectors and single-chip DLP projectors with superb contrast. These days, the most fierce competition occurs in the $1500-$2500 price bracket, so if you can afford something in this range, your options are almost limitless.
$4000 and up: There are, of course, many high-performance 1080p projectors available at or beyond this price. 1080p projectors, when coupled with high-definition signal sources, offer the ultimate in HD home theater at the present time. However, this range is devoted to products for the video connoisseur, who values small improvements in picture quality and is willing to pay extra to attain them. If you're just looking for the "best bang for the buck," step back down to the $1000-$4000 category.
Replacement Lamps
A projector is not like the television in your living room. While the family TV can be left on almost indefinitely, projector lamps have a finite life before they must be replaced. Lamps usually cost $300 to $400. Most projectors have maximum lamp life stated in the specifications, but some don't. In any event, a specification of, say, 3,000 hours does not guarantee that that lamp will in fact last that long-what it does guarantee is that you cannot run it longer than 3,000 hours. But it may fail early, requiring a replacement. In addition, as a high pressure lamp ages, its light output diminishes. Many users choose to replace their lamps more frequently than the maximum life in order to maintain a brighter picture.
Lamp expenses should be planned for, and you may want to purchase a spare lamp when you purchase your projector. This will minimize downtime of your projector when your lamp needs replacement. If you plan for the expense of lamps ahead of time, you won't feel blindsided by an additional $400 out of pocket later on down the line.

但是现在看来我是没有动这个坏脑筋的退货打算了，因为用了就知道：超值啊。
