The Galileoscope is pretty cool
I picked this up from the Bad Astronomy blog (which I love) – the Galileoscope. Galileo used his telescope to discover 4 moons of Jupiter, observe Saturn’s rings, and look at the Moon. For the International Year of Astronomy 2009, a group of astronomers and educators created a replica of Galileo’s telescope. I just ordered 2, so my girlfriend and I can both go out and look at the same thing without having to pass it back and forth. They’re only 15 dollars a piece and extremely easy to assemble, plus the whole thing is for a great cause. You can even donate Galileoscopes through the website easily and for a cheaper price ($12.50 instead of $15.00).
