Guys!
I have an epson 640 printer and use ink from
http://www.choicestationery.com/acat...olour_440.html which costs £14.49 for 4 colour and 4 black cartridges...and it is PERFECT.
They seem to supply ink for a range of printers. AND it arrived by post the next day.
SERIOUSLY worth trying...
Cheers...
