I went with the p25 over the p30. I did not need the faster shooting and wanted to have the bigger CCD. Wanted to be as close to full frame as possible to get the most out of my 35mm. Also I was told that the p25 will have a better trade in value when looking to upgrade. If you are more about speed and higher ISO I would go with the p30+.
