Something like the Sparkfun 6-axis IMU would work, which is $300 when you drop the bluetooth module ( http://www.sparkfun.com/commerce/pro...roducts_id=411 ).

I don't think you are going to find an off-the-shelf 6-axis sensor for $200. I think you need to rethink your requirements, as anything in the "affordable" range isn't going to be sufficient to use for navigation. I hope this isn't going to be the only source of navigation information for whatever project you are going to use this on - as gyro's and accelerometers both have drift issues.

You can pick up three ADXRS300EB's from analog devices for like $50 each, plus accelerometer(s) by Freescale, Analog, etc and build one yourself, simply on PCB or something. Shouldn't require that much mechanical skill. (Sparkfun sells the Freescale 3-axis thats on the IMU board for like $40 IIRC).
