hi!
I am new to this foram but I hope I can help
If you are going for the best in color photographs, IMO you can't go wrong with Epson photo printer.
As far as 3+black ink or 5+black ink printers, I owned both and the 6 ink printer does have better transitions in grays, and better looking flesh tones.
In the past the less you paid for the printer, the more it costs for inks.
Now epson makes a printer for around 199 dollars that has separate wells for each ink.
If money is not a big concern, epson also has 7 ink printers for even more realistic photographs
