Im considering two DSLR's but can't quite decide which one would be the best bang for the buck: D70 or 20D. The main uses will be sunsets, scenary, car photos, action shots (sports) and random pics. I currently work with Nikons and prefer the direction of zoom on the lens as opposed to the Canon but the Canon does 5fps vs. 3fps and is 8mp vs. 6mp. The d70 doesn't go down to ISO 100; the Canon uses CMOS vs. CCD. These are all things i've considered but I need to determine if they are relative to my uses. Is CMOS better/worse than CCD; is ISO at 100 that important for "general" use? Do I really need 2 more megapixels?
