Am having to ditch my Epson C80 due to clogged heads. So I would suggest sticking to originals. I have suggested PC Advisor should do a thorough review of compatibles - but I guess it would be no easy task.
MFL not so sure the problem is with compatibles, I and a mate both have Epsons, mine is a year older than his and I've always used Choice Stationery compatibles, its still going strong, his always used Epson originals and its all clogged up, mine has probably had a bit more use than his whether that may have something to do with it or not I don't know. I too would like to see a review of compatibles in actual use but I suppose its impractical to do this as its necessary to do it over a long period of time.
