I'm a newbie to this site, though a long-time hobbyist, and have learned so much from everyone's comments. I'm surprised no one has mentioned that the questioner might want to consider that moving up to a camera that produces double to triple the file sizes he's used to dealing with may have an impact on his workflow, depending on the computer setup he's accustomed to. I've run into this problem as I've upgraded my cameras from time to time. Just something to keep in mind during decision-making, I think.
