Arduino scale?

Curious if anybody's tried interfacing with a cheap digital kitchen scale.

Seems like a good way to deal with some food/beverage dispensing issues...

I have wondered about pulling the brains out of my current digital kitchen scale and replacing them with an Arduino. If you could use the existing force sensor and lcd, it would be an easy way to go. Then I could have the scale default to my favorite units and push the auto shutoff up to something like 15 minutes! I hate it when mine shuts off in the middle of a measurement.
