Although I am mostly interested in high end black and white, I also do print some color. I never use the OEM solutions. I've used MIS Associates (
www.inksupply.com) for years as a source of empty, refillable carts. I also now purchase from STS Inks. Frankly, if I were in the market for a printer, my search would start with the question of which Epson printers were supported by good refillable cartridges from these suppliers (or other suppliers who are going to be around for a long time).
Note that I favor Epson printers because the piezo heads are compatible with the most third party inks. I've also formulated (and published the formula for) a generic dilution base for the Epson printers. The color toner I use to neutralize the warm carbon inks in my B&W systems is, for example, composed of Canon color pigments diluted in the generic base.
FWIW,
