As the pace of technology marches towards its time machine/realistic pocket-vagina zenith, obsolete gadgets will join your laser-disc player in the piles of dead electronics overrunning your home. Turn that unloved circuitry into bundles of cash with Second Rotation.

SR's a new online exchange service that hands you brand new dollar bills in return for unwanted electronics -- 2500 models are welcome, including cameras, MP3 players, and cell phones (but not the Tamagotchis on your nightstand, who'll continue to watch you sleep as they starve). The process: just search SR's database and if they lust for what you have, their Dynamic Pricing Calculator'll walk you through a step-by-step assessment of its ultimate worth/near-worthlessness. Payoffs range from $10 for a lifeless iPod Shuffle to $70 for a reasonably functional Razr to over $800 for a Canon digital SLR fit for Annie Liebowitz/Joe Francis.

Once you've worked out a deal, SR'll have a DHL guy scurry over to your home/office/unregistered box truck to pick up your junk, gratis -- though he might chuckle when you hand him your broken-down, alpha-version vagina.
