Looking for recommendations for simple MEMS rate gyros and supporting curcuitry

For the price of one seat of Matlab with Simulink you can get five or
ten Crista IMU's from Cloudcap technologies,
http://www.cloudcaptech.com .  Toss in the Control Systems Toolbox and
you can get a few more.  These are Analog Devices MEMS sensors that have
been calibrated over temperature and integrated with a microprocessor
for friendly communications.  I think it'll meet your stated needs --
its up to you to see if it's accurate and quiet enough.

Check out sparkfun.com, or more specifically,
http://www.sparkfun.com/commerce/categories.php?cPath#_80

They have 6 dof systems.

If you go this route, many of these have analog outputs, unfortunately,
but a microcontroller circuit that would spit out the values at a
constant rate shouldn't be a big deal to farm out.  Also, make sure you
get a breakout board, as the chips themselves can be nasty to solder
(BGA, and all that).

A second look reveals serial appliances further down the same page!!  
Huzzah!

Let me know if I can be of help.

Oops, my wandering took me off the page.  Check out
http://www.sparkfun.com/commerce/categories.php?cPath#_85  for gyros.

You may still need to farm out the serial interface, but my guess is the
ucontroller nerds at Sparkfun would be happy to set you up at nominal
prices.  I'd do it myself if you're really stuck, but it might take a bit
of time.

This looks pretty interesting. They even have a Bluetooth wireless
version -- that is about exactly what I need. Thanks for the reference.
