Thanks for the responses going to do some more research on this. I am currently using a cheap Panasonic, which is OK for bright outdoor work, but really struggles in low light conditions. So trying to upgrade to hi def and spend as much as I can afford on a higher quality camera.
With regards to iMovie 08, i have just read on appleinsider, some scathing early reports on the lower functionality of iMovie 08. Was going to upgrade immeadiatley, but will try a demo in the shop before I buy now! I called the apple store in Batutta mall and was told wait for a month.
So will struggle on with the old faithful Panasonic for the time being and 06!
