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

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

Please share some of that pressure data you are collecting on you engine Finn.

Haven't implemented the data logging/dumping feature I talked about yet. Any year now :)
