Where can we buy the gyro?

We’re searching for gyros that are authorized by the competition rules. We’ve found AD22304. So, where exactly can we buy it, and can you recommend better gyros?

Sparkfun Electronics is a great source. The URL is http://www.sparkfun.com. The ADXRS150 and ADXRS300 are excellent devices and if you’re using my code, support for these devices are built in.
