Here's the links to the HC42 and HC90. I read a thread comparing these two, but didn't get a feel for the overall picture quality difference from it. http://www.sonystyle.com/is-bin/INTERSHOP.enfinity/eCS/Store/en/-/USD/SY_DisplayProductInformation-Start?ProductSKU=DCRHC42&Dept=cameras&CategoryName=dcc_DICamcorders_MiniDVHandycamCamcorders http://www.sonystyle.com/is-bin/INTERSHOP.enfinity/eCS/Store/en/-/USD/SY_DisplayProductInformation-Start?ProductSKU=DCRHC90&Dept=cameras&CategoryName=dcc_DICamcorders_MiniDVHandycamCamcorders Are you afraid of dying...or just afraid to live?

I'm looking at two cameras, one with 1MB and the other with 3MB pixel counts, and wondering if the cost difference is justified by the higher count. Can anybody describe the "real world" difference in picture quality between the two, specifically for skydiving application? Also, what is the difference between Gross and Actual pixels in the specs? Thanks in advance for for your input. Are you afraid of dying...or just afraid to live?
