I have an Epson 310 that I bought earlier this year. And I bought the non-oem refillable ink cartridges that just came out in the spring. I never had any real luck with the cartridge refills with my old Lexmark. The Epson cartridges are expensive. With the refillables, I have printed TONS of stuff since I got this printer and I am still on the original bottles of refill ink. And the cost for the whole set of 5 bottles costs less than $20 including shipping. Yes, it screws up the warranty stuff on the printer but the printer only cost $100 to begin with. I more than make up the cost of having to buy a new printer when I have a problem with the savings on the ink.
The other thing that I really like about it is it is a straight feed printer. The material being printed on does not have to twist and turn, just feeds straight through. A big help when trying to print on fabric, envelopes, etc.
