According to:

http://www.instrumart.com/products/38140/setra-270-pressure-transducer

this Setra pressure sensor pricing starts at $1738.00  I wouldn't call that inexpensive.

What I would call inexpensive ($58) is the TI eZ420-Chronos Development tool which includes a MSP430 series micropower microprocessor in a watch case with Bluetooth link to your PC.  Besides a built-in temperature sensor, a 3-axis accelerometer,  it also includes a pressure sensor which can read the height of your head, right out of the box.  Mind you it wouldn't be accurate enough for serious weather measurements of barometric pressure.
