Dye and Pigment ink for Epsons printers

Hello to everyone,

sorry for my bad english ..
I have one Epson Stylus Photo 1400 and to pick up a PRO 3880

I read various discussions about (with the help of Ink Stained Fingers ---> Thanks) but I do not have clear ideas
so if you can kindly help me I would be grateful:
1) what do you think is the best ink non-OEM for the 1400 ?
2) it is advisable in terms of quality convert the 3880 in DYE?
3) which ink pigments (always non-OEM) and cartridges , do I recommend

thanks to any information...
