Alboni,

I have had a number of occasions to use accelometers from the ANALOG
DEVICES accelerometer product line.  While you may not consider them low in
price I have found them to be low in installed cost for small volume
installations.  My early experience was that many of the parts were very
difficult to obtain because of production capacity limitations, however
production has apparently been ramped up to where I haven not had any
problems obtaining them from suppliers.

In addition the data sheets are well written, including discussions of the
devices limitations and where possible workarounds to these limitations.
The application notes are also well written and have a number of real world
practical examples.  The application engineers have also been accessable
and very helpful in the past.

Much of the first stage interface and signal conditioning circuit in on the
device making implementation farily straightforward.
