Look! A CubeSat!
It's a miniature satellite made from off-the-shelf consumer-grade electronics components, with a volume of exactly 1 litre, a weight of no more than 1 kilograms and a price tag of between $65,000 - 85,000 (I suspect the price depends mostly on whether you opt for a laser-etched Decepticon insignia).
So for the price of a luxury car, you can put a small but very real payload into orbit! And many university astronomy and engineering departments have done just that since 1999, when the CubeSat was coined / invented by students at CalPoly and Stanford Universities.
You can either build and case-mod one of your own (finally a good way to get rid of that old GameCube), or you can just be lazy and get one from Boeing, but the latter route is likely to cost more.
Good luck getting NASA to launch your nanosatellite, though. Despite the low price tag, there's apparently a lot of red tape since a Dnepr rocket carrying 14 adorable little nanosatellites exploded at launch in 2006. Poor little guys.
The next nanosatellite launch by NASA is in November 2009, leaving just enough time to clone your DNA and get it out of Earth's orbit before the Large Hadron Collider kills us all!
