While you can find the BEI Gyro that was included in the kit a couple of years ago available from a company, the cost is in excess of the single electronics component limit. I suggest spending the ~$60 on the Analog Devices gyro part number ADXRS150EB. It is a simple yet stable gyro to use and program and is robust enough where it will last a few years and will be able to be used on future robots.
