Data Logging Accelerometers

I'm in the process of designing a datalogging system for a club race car.
The car is fitted with Haltech F7 Fuel injection. I have an 11 channel A-D 
converter which plugs into the parallel port of a laptop which will be in
the car.
The converter can sample at up to 18kHz @ 10 bit resolution (386 laptop).
I'm going to interface some transducers to it. I'm currently thinking of:

        Throttle position (rotary potentiometer)
        Steering angle  (   "              "           )
        RPM (from tacho output)
        2 x wheel speed (proximity sensors)
        3 axis acceleration

I would ideally like to incorporate suspension movement as well, but may be 
limited by budget as I am a university student.

Would anyone know of a 'budget' accelerometer. It could be single or multi axis.
It must be able to measure static acceleration.

Any other comments would also be appreciated.

Thanks,
