Kiwi, 

Quite honestly, I really cannot recommend a camera based on printing needs.  As stated in previoius postings, there is much more to getting a fine print than the camera used for the original image.   

My one summarized recommendation is to see what your direction might be, while being aware that may very well change.  Choose a camera suited to what you really want to accomplish and know that camera is quite capable of going other directions "with you".   Stay within a budget fitting what you actually can spend with some for unforseen needs, such as another lens, etc., beyond the basics of tripod, extra battteries and memory cards.  You might want software upgrades, for instance, which are  not always inexpensive even if less than a new lens might be.

I see most of the newer DSLRs quite capable of doing what you want to do, with room for other attentions as those enter your growth in this field.    I am changing in my directions, not knowing a specific direction in the first place beyond wanting to "be better at the first shot".   My camera will do the job when I get better and better.   Best wishes again on your quest.             Tom.
