Epson - SureColor P5370

Epson L8050 is pro-sumer at best, D700 replaced by D1000. This gives you duplex printing in high quality, and quantity but somewhat restricted in print sizes (Max print width is A4 or 210mm). I would suggest a SurePress P5300 - A2 width, more inks, roll and sheet, professional

The Epson P700 is one of the best options, print quality wise. The two main downsides are small lightweight flimsy construction of the printer, and unexpectedly high cost for ink. The latter is easily fixed by going for the bigger brother P900. It's 17" and accepts larger cartridges, bringing the price per mL of ink back into normal regions. Fixing the flimsy construction problem isn't possible within your budget, at least not if you want to keep the "the best photo printer" quality requirement. You can get more robust printers, but not nearly as good ones unless you pay much more. The real fix is the P5300, which contains the same print technology, but in a sturdy metal chassis. It's built like a tank and requires two friends to help you move it around.
