Apr. 13, 2007 (KABC-TV) - Teenagers just have to have the latest high-tech gadget -- anything else is so last year. To keep up with today's greatest, some teens put their old stuff up for sale. Some of these sales are safe, others can be risky moves.

Eighteen-year-old Greg Stoft loves to skate the streets. But recently he wanted a new set of wheels and didn't have the dough. So he decided to sell his used iPod online.

Stoft is part of an exploding number of teens earning extra cash, one sale at a time. Using sites like MySpace, Craigslist and eBay, these mini-entrepreneurs hock everything from MP3 players to laptops to digital cameras.

Sounds like a good business deal. But Internet safety experts like Marsali Hancock of KeepSafe.org are extremely concerned. They say the desire to sell is so huge, kids are forgetting the basic rules of Internet safety.

What can you do as a parent? Hancock says you should keep communication lines with your kids open. That way you can be involved in your child's sale from beginning to end.

Hancock also recommends working with your teen on an established auction platform like eBay, which requires you to be 18-years-old to have an account.

Platforms like PayPal or Google checkout. Even though Greg is eighteen, he decided to go with Craigslist and says, luckily, the sale went just as smooth as his new ride.

If your teen is planning on selling a cell phone or laptop, make sure they wipe out all personal information before shipping. That way no one else can get their hands on sensitive data.
