(sorta talking to myself ....)
Well, I thought my decision was made, but things took a little turn.
More research (a good thing) strongly pointed towards using a macro lens for copy work due to their very flat field/sharp focus/minimal distortion edge-to-edge. I have a 100mm macro, but on a 1.6 crop, the working distance on 30"+ subjects is a bit unwieldy.
So, that leaves me with the conundrum of
1) 7D + DXO Standard ($169)+ EF 50mm f/2.5 Compact Macro = 1884
2) 6D + DXO Elite ($299 grrr) and use already owed EF 100mm f/2.8 USM = $2160
7D option also lets me use my EF-S 18-85, while the 6D leaves me with only the 100 mm and 50 mm (F/1.8) till I save up for another zoom.
Must think more....
Why add the price of DXO? DPP comes free with the camera, whichever one you choose. Personally, for photographing large artworks I'd probably go with the 6D and your existing 100mm f/2.8, and forget about the DXO software. If you want to put money where it will help, buy a color calibrating system such as X-Rite's, to help ensure accurate color reproduction in the finished images. Also, if you don't have one, a good tripod will probably be pretty essential for taking first-rate shots of paintings.
