Epson XP-850 or XP-860?

[timw128]

Hello- I need to buy a new back up printer. My Artisan 810 is sick and I don't know yet if it is terminal. It has been a very good printer and had exceptional photo quality. With that said, I am pretty much set on the 6 color dye based ink.
My question, can anyone chime in on the Epson XP-850 and XP-860 printers?...
Do they take well to a CIS system?...
If anyone knows where I can find an NOS Epson Artisan 837, please let me know.
Thanks to everyone for the time and consideration.
Regards-
