I have used an accelerometer from IC Sensors in a datalogging application.
The model is a 3028-002. It measures from +/- 2.2 g. Each unit comes with a
circuit for temperature compensation and linearisation which reduces the
error to around 0.5% from 0 to 1khz 0-50 degrees C. They are single axis and
fairly pricey I think. The sales rep gave me three free samples so I never
found out what the price was. :)

I can give you more info, circuit diagrams etc. if you require.
