The two I'd suggest you look at first are the 3880 and the 4900.
The 4900 is bigger, heavier, and has a larger gamut (uses more inks). It also uses larger cartridges, so fewer changes. It supports cut sheets and roll feed.
The 3880 is cheaper, effective, and there are profiles for lots of different papers. Cut sheets only.
yeah those (or R3000, costs a lot less, but the ink does cost more and it prints smaller)
R3000 is amazingly resistant to ink clogs compred to my miserable old R800, which would clog hideously badly all the time, a nightmare of cleaning kits, or using up entire ink sets on cleaning cycles, buying an R3000 pays for itself compared to an ink hogger clogger
