Solid State Gyroscopes
Here's a comparison of current (2006/05/03) obtainable MEMs gyroscopes. Here's a good resource for seeing who's making gyroscopes these days.
Cheap (Basically Useless)
These gyroscops are good shake sensors, but they're basically unusable for IMUs.

Middling (Probably Useful)
| Mfg. | Model | Cost | Noise | Sensitivity | Range | Bandwidth | Vcc | Temp? |
|---|---|---|---|---|---|---|---|---|
| Invensense | IDG-300 | $50 | 0.014 °/s/√Hz | 2 mV/°/s | ±500 °/s | 140 Hz | 3.3V - 5V | N |
| Analog Devices | ADXRS150 | $50 | 0.050 °/s/√Hz | 12.5 mV/°/s | ±150 °/s | 40 Hz | 5V | Y |
5°/s/√Hz
Expensive (If Only)
