My favorites are the solid state micro-machined accelerometers from Analog
Devices as can be seen at: http://www.analog.com/pdf/preview/ADXL105_a.gif
They have low power consumption (2mA), and are small (surface mount) and can be
used for tilt *and* vibration with different filter models; also they are cheap
(even free if you ask them nicely for a couple of samples).
