R2880, I have had one for a year or so now, excellent results but I personally would steer clear of copy ink or continuos systems. The reason I had to buy R2880 was my old Epson printer clogged the heads with crap ink! I argued with the continuos systems sales people at Focus last year about the problems with their inks, even the samples printed for display purposes at the exhibition had lateral lines through suggesting clogged ink jets!
I buy ink from Espon website at £11.57 per colour with free delivery.
