Arduino Strain Gagues

I'm trying to use strain gauges to measure vibrations and would like to use an arduino. Has anyone used strain gauges with an arduino before or know of any tutorials to do so?

These guys have done it:

I plan to do strain gauges next summer if I find time (I have model Rockets)
