While I was sourcing some I2C Chips I came across this I2C High-Precision Pressure Sensor - HP03D
High accuracy, low-cost pressure sensor, ideal for use with weather stations, altimeters and pressure measurement. The unit is fully digital with a 16-Bit ADC on board, with 15-Bit accuracy together with a measurement accuracy of 0.5hpa. Easy to interface to any microcontroller with a standard I²C interface. The unit requires only 3V and full installation instructions are available in the datasheet attached below.
• Pressure Range 300-1100hpa
• 16 Bit ADC
• I²C Serial Interface
• Accurate to 0.5hpa
• Supply Voltage: 2.2 - 3.6V
It's available from Futurlec, http://www.futurlec.com for $9.90.

Looks great. I am working together with Brian Davis to make an NXT sensor with the SCP1000 pressure/temp sensor. It's a lot more expensive than the one you suggested, though. Here's a copy and paste from the product page.
We're using the I2C break-outs that you can get from Digikey for about $60 us. We're also using the Sparkfun logic level converter to make sure we're not going to kill our sensors with 4.8V when they can only handle up to about 3.3V.
