I'm gonna think about maybe a lower cost/simpler alternative to a gyro, maybe a feeler attached to a pot? If you have any suggestions feel free to post =)
EDIT: Or anyone know how I can build something similar to http://www.sparkfun.com/shop/index.p...s=ACL-IMU-203& for cheaper?

The sparkfun IMU is neat in that it is all on one board, but you can get evaluation board versions of the same things from Analog Devices (
www.analog.com). You can probably save $30-$50 by buying separate EB's instead, but you aren't going to get comparable performance for much less. Make sure you buy EB's or something with the devices mounted. The gyro's are all ballgrid and aren't worth the trouble of mounting yourself, you can solder the accelerometers as they are a small surface mount pitch but its still easier to buy EB's that have all the resistors and caps installed that you need.
As far as something simplier/cheaper, I've seen people attempt the same design using two IR distance sensors on each side.
