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[°·s-1·Hz-1] | Sensitivity[mV·°-1·s-1] | Range[°·s-1] | Bandwidth[Hz] | Vcc[V] | Temp |
|---|---|---|---|---|---|---|---|---|
| Invensense | IDG-300 | $50 | 0.014 | 2 | ±500 | 140 | 3.3-5 | No |
| Analog Devices | ADXRS150 | $50 | 0.050 | 12.5 | ±150 | 40 | 5 | Yes |
Expensive (If Only)
