RE: A little off topic.......
Well, what I've read so far from the others,--- they're all right-on with their suggestions. They'll both do what you have specified them to be doing. All in all, it's up to you. I will make one minor adjustment to one comment - and that is in regard to the MP that you need. I believe I read that you will need at least 4MP -- true enough. However, if you want to be doing any "critical" printing that requires DETAIL in the BLACK areas, I would go to 5 MP- maybe even 6MP. If not then 4MP will be absolutely enough.
Best of luck to you
