it may be one of the more cost-effective printers but the cost to replace all 4 cartridges still will cost close to $100. For the same $100 I can get multiple refills with the non-Epson branded ink. So that's why I'm asking, since I've never used these replacement cartridges with non-brand ink.
I also have an Epson R1800 printer that I use occasionally. If what InkXpro is selling is reliable I'd consider using their pigment ink in that one, too.
