Rent or buy? That's the question these days for everything from real estate to music and DVDs. And with the price of even mediocre digital camcorders still too high for most folks, it was only a matter of time until a more affordable solution appeared. CVS is the first to reach the market, with the One-Time-Use Video Camcorder ($30 street): You buy it from your local CVS drugstore, shoot your video, and return it to the store for processing to DVD (a $13 fee), after which CVS repackages it and sells it again. Think of it as renting with no late fees, or a disposable camera that CVS doesn't actually dispose of when you're done with it.
