Hi Dave......good luck with it.
Kodak makes great stuff....my buddy works on the QE2 cruise ship and uses a ZX1 all the time to send me videos around the world...I was so impressed by the picture Quality and Sound & that the Zx1 uses TWO AA batteries or included Rechartgables I had to have one and at half price I couldn't resist....The Zi8 is a newer model and certainly has a few better specs that you mention. I like the editing Arcsoft software also easy to use....it's all good enjoy. Hope to see some of your videos playing also.

Happy Happy New Year
