Given your mentioned desire for 11x14" prints, this means a 13" carriage (13x19") printer. Since you also haven't mentioned black-and-white printing at all, the choice of printers is relatively wide.
Both Epson and HP make a few printers in the $400-600 range that can do the job. I've been rather partial to HP the last few years.
This HP printer has been well-received, with just a few less features than
this one (but both are on sale at the moment).
On the Epson side,
this model is the only one that holds my interest. The
2880, on the other hand, now appears to offer smaller ink carts than its predecessor (2800), and I have the sinking feeling that those smaller carts aren't any cheaper than the 2800's. The HPs I've linked to, on the other hand, have
huge ink carts; so big, in fact, that they are separated from the print heads via hoses, just like the big-bruiser jobs both companies make. Something to think about.
Another thing to think about, which was one reason I switched from Epson to HP: Epson's heads are permanently mounted in the printer, which means that if a print-head-related problem should crop up, you have to ship the entire printer off to an Epson service center. HP's print heads are user-replaceable, which for me is a big deal. If a head goes bad, simply replace it with a new one. The printers monitor head condition and can give you a heads-up in case there's a problem. In addition, each of these HPs has a closed-loop calibration system, just as on the big boys, which makes proper color calibration easier.
That's my take on it. There'll be a lot more from others that's worth reading.
