Home theatre enthusiasts say you can get the best bang for your buck with a system that uses a digital projector. They can easily be hooked up to your computer, video game system or DVD player or cable signal and display images in a variety of sizes.
These days, high-quality home theatre projectors by makers like Mitsubishi and Samsung sell for as little as US$850.
If you're on a tight budget, you can set up your projector in your apartment or dorm room by simply directing it towards the wall. If you want a more impressive display, you can buy a screen (measured at 70 to 200 inches diagonally).
These screens, made by companies such as Elite Screens and Da-Lite, cost anywhere from US$225 to more than US$3,000 for deluxe models that have a motor to retract the screen into an aluminum casing.
There are some downsides to projection systems: They use a specialized bulb that needs to be replaced every few years for around US$350. Another drawback is that projection systems work far better in a dark room. So if you don't have a windowless basement, or a room with dark shades, you're probably better off with a plasma or LCD (liquid crystal display).
Plasma TVs and LCD sets look alike but actually use different technology. Plasma screens use a gas that's charged by electricity, while LCD screens create images by charging a different material: liquid crystal.
Some experts prefer plasma screens because they display better black hues, have sharper images and can be viewed from all angles, but the TVs have a shiny screen, making it harder to see the picture if there's a lot of light in the room. They also are big energy hogs: Consumer Reports says its tests show that plasma sets use up about twice as much energy as comparable LCD screens.
Experts say LCD technology is better for a bright room, though fast-moving images can blur a bit and the image often doesn't look great if viewed from an angle.
Prices of flat-screen TVs -- made by dozens of companies like Samsung, Sony, Panasonic, LG, Olevia and Vizio -- dropped dramatically in recent years. It's even possible that 32-inch LCD TV sets, which now usually cost US$600 to US$700, could drop to as low as US$350 in stores by the end of 2009, analysts say.
Regardless of which one you're inclined to pick, experts advise taking your time and inspecting the television's picture carefully to examine the brightness and colour.
Before deciding to buy, bring your favourite DVD to the store and test it out on a new set, advises home theatre designer Brian Lamont of Presque Isle, Maine.
"If they won't allow you, say 'thank you very much' and go someplace else," said Lamont, who has designed projects around the country.
There's also a lot you can do to make it easier to choose a movie from your collection. Massive media servers -- basically giant computer disk drives -- make it easy to sort through hundreds of movies, sorting it by actor, genre and the like.
Apple Inc.'s Apple TV starts at US$229. A competing Internet set-top box from Vudu Inc. that launched last fall has roughly 5,000 movies available and sells for US$295.
"You don't have to remember where all the DVDs are," said Lewis Franke, a home theatre systems designer with DM Home Entertainment in Carrolton, Texas.
