Why BMP180.

At present, I have chosen to go with the bmp180 sensor over the ms5611 sensor. I am aware of the very high accuracy of the ms5611. 

My reasons for the bmp180:
- 8x lower price
- already have code for it
- when interfaced with atmega328 3.3v (@8mhz), the bmp180 will run at (3.5mhz). I feel the 20mhz of the ms5611 will not be utilised effectively by the atmega chip, so a little bit pointless?

Maybe in the future, or to use in a flight controller, the ms5611 seems good. For the case of a ghetto-cheap altimeter-osd the bmp180 is ok.
