Hi, I just bought my dream camera a few days ago from best buy: the canon 30d! The question is: is the warranty worth it or needed? It's 250$ canadian for 3 years and it covers the camera itself in terms of screen or buttons etc. Some have told me that the warranty is not really needed coz the canon 30d is a solid camera and i should not worry about the parts breaking. also: how do u turn on the lcd screen so that u can take live pictures with it? is this possible? right now, i can only take pics using the viewfinder. thanks a lot.
