The ADXRS300EB is essentially equivalent to the SparkFun card. We placed ours in a standard 20-pin IC socket in order to avoid soldering directly to the board.
Disclaimer: I have no association whatsoever with Digikey, other than having ordered an ADXRS300EB earlier this week so that we'd have two -- one to use on both of Team 1519's two robot configurations. It arrived in a couple days as expected.

PS: For what it's worth, the 2.25 laps (9 lines) of autonomous in 15 seconds that we do with Speed Racer uses Kevin's gryo code with an ADXRS150, used "as a compass." There are three completely separate runs in the video. We're not sure how much of our error is due to using only a 150-degree/second gyro; we think that most of the trouble we have with driving a straight line is due to the "steering lag" in the closed loop control. For bias calibration, we use Kevin's routine while the robot is disabled as he describes above.

Yes, the ADXRS300EB will work too, but requires some additional soldering, and mounting is a problem too. The SparkFun board is almost ready to go and can be attached with double-sided foam tape.
