Solid-state gyro sensors boards with analog or serial output would complement your accelerometer boards very nicely.
There are a couple of vendors for the sensor ICs...

FWIW, I have used gyros in radio controlled helicopters and products based on the Siliconsensing devices seem to be far superior to everything else (well, maybe the $1000 sensors work better, but who cares about those?). The "center" signal for other sensors drifts over time - after 15 minutes the gyro indicates that it's rotating when it really isn't. If you integrate the signal over time (as good heli gyros do) the error gets really obvious. The SS sensors don't seem to have that problem. I have no idea what the individual parts cost but if they cost a few bucks more it would be worth it.
