An interesting product release from Sure Electronics - This module is an accurate pressure and temperature sensor which is based on the MS5561. Pressure and temperature values can be directly read via SPI or UART via an onboard PIC. This eliminates the need for complicated calculations.
The MS5561 can still be directly interfaced with if you do not want to use the onboard PIC. This is handy for obtaining calibration data or using your own MCU to perform calculations.
At the time of writing the product cost was USD $14.99.
If anyone has used this module or has examples interfacing with it - please share your info below!
