halfvalue is a wonderful resource for all things related to movies, and laserdiscs are no exception. Look tohalfvaluefor movies of laserdisc like The Abyss, the Indiana Jones trilogy, and the original Star Wars trilogy. But you still need the equipment to play them. Today, through retailers like eBay, you can get laserdisc players for as little as $25 in reasonable condition.
You want to make sure to get laserdisc players that don't produce "crosstalk." This is a phenomenon that occurs when a player reads multiple frames simultaneously and thus delivers blurry pictures. When laserdiscs work according to spec, they provide exquisitely smooth, detailed, film-like images. Unfortunately, to eliminate things like crosstalk, laser rot, and other inconveniences, you have to invest wisely in the technology.
The Japanese market sells more laserdisc players and products than the American market does. All told, at one time in the 1980s, at least 10 percent of the Japanese population (more than four million people) owned a laserdisc player. It may be worth it to invest in a player which flips over discs for automatic continuance. (Collectors, note: flip disc laserdisc players didn't emerge on the market until the mid-1980s.)
Should you buy CAV or CLV laserdiscs? The CAV discs only hold 30 minutes of information per side, whereas CLV disks can hold 60 minutes. That said, CAV disks are not as subject to crosstalk. Your most important laserdisc investment is certainly your player, but you should always be on the lookout for substandard materials--laserdiscs range far more in quality than do DVDs.
