I buy mine from www.newark.com. About $20.
I prefer the MPX5xxx series. You feed it 5 volts and get a radiometric

(linear)

output to pressure with a known offset.
Motorola has apparently changed their web site so an overview of

pressure sensors

is harder to find, but see

http://e-www.motorola.com/webapp/sps/site/prod_summary.jsp?code=MPX5999&nodeId=01M98716

Make sure you get the DP or P types (ported).

Thanks a LOT Finn... that is more like what I need.
