     How about the ADXL202 from Analog devices.  It's a 2 channel Stati=
c
     reading accelerometer that outputs acceleration as a duty cycle, i=
t
     only requires a couple of caps. and a resistor to set the
     frequency.  It would be simple to interface to a PIC & in fact the=
y
     (analog devices) sell an evaluation kit that uses a pic to
     re-transmit the X & Y acceleration values via RS232 to a PC.

     Rough pricing in English pounds

     ADXL202 1 off          ~ =A316


     The documentaion is good, they even have code examples for PICs &
     an vewry simple PC joystick interface using just a couple of caps.=

     to smooth out the pulse outputs.

     See their Web site - www.analog.com for more details.

     P.S. I have no connection with AD, I just like their products!
