You can score some great deals shopping online, especially if you want to go the EBay route. But this laptop stand (normally $29.99) from Logitech is on sale for a gasp-inducing $4.99 at Amazon.com right now.
The Logitech Alto Express Notebook Stand is a clear stand that supports itself on the table (and your laptop on the stand) with rubberized feet. It's got a slightly convex shape, giving you a little help with cord management and allowing air to circulate underneath your machine.
Due to it's great bones, we've already featured the Logitech Alto Express Notebook Stand on Unplggd as a great buy even at full price.
It's a fixed piece, though, so there's no adjustments for comfort. We think it would be a great desktop stand for somebody using it with a second keyboard—or even a a second monitor setup.
