I too used to get the blue finger as I called it from refilling. My solution was to purchase a CISS (Continuous Ink Supply System) for my Epson which cost me about £40 which included 6 X 250 ml bottles of ink (1 of each colour). Refilling them is so easy and I seldom have to do it more than once a year. 2 years later I am still on the original ink bottles and I still have enough left for at least another year. I do a lot of A4 photos so I do use it a lot so for £40 or so I recomend it to you. You can get systems for many different printers so I would google CISS and see what you can find. I used to pay nearly £50 for a B/W and 3 colour HP cartridge which would hardly last 5 minutes.
