Hello wonderfull world of piclisters !

I know this question has been already dicussed, but everything move .

I' am on a little project & i need some info about a shock/accelerometer
sensor, who should be, as possible :

- small
- light
- (cheap)
- (interfacable to a PIC)

But i don't requiere a lot of precision, just one axis, not a lot of G's
strengh .

Is someone know that thing ?

(please excuse my poor language !)
