Buy a Galileoscope! *Update* It's HERE!
2009 is the International Astronomical Union's International Year of Astronomy, in recognition of both Galileo's first recorded astronomical observations and Kepler's publishing Astronomia Nova. As a part of this whole thing, the Galileoscope was created.
Although most astronomers/telescope enthusiasts discourage buying telescopes of this size, because they are usually crap, and just discourage you with lousy views, this one was designed by professional astronomers. While it is largely plastic to keep costs down, the lenses are high-quality glass achromatic doublet lenses, which are usually found in much more expensive 'scopes. The other cool part about this project is that you can anonymously donate a telescope, and it will be sent to someone who can use it, whether it's a homeschooling family in Iowa or a schoolhouse in southeast Asia.
Oh, and the best part: the telescope is $15. You really can't beat that price, and shipping is only $8.95 in the US. If you donate one, it's $12.50 with no shipping charges. I bought one, even though I have a larger telescope, as a more portable one for quick peeks at planets and to take on trips.
Buy one! Or two! And donate some! They're cheap!
Update 30 Aug 09: due to increased manufacturing costs since they started production, the price has been raised to $20 plus shipping to buy one, and $15 with no shipping to donate one. Still a heck of a deal, though.
Second Update 2 September 09: ZOMG IT'S HERE! I should have just ordered the thing when I first heard about it. I was order #22,670, and the first 20,000 were shipped in mid-June. I have it, though, and I'll be posting an Instructable with assembly instructions as soon as I get around to it, and pictures taken through it once this stupid overcast blows over.
