Hi Garri
my advice would be to take a long hard look at your budget and think seriously about the 4800.
I have a 2100 and a 7800 and I now just use the 2100 for printing out correspondence and internet stuff, it makes me wince when I think what I paid for the machine and how much I've paid for ink since.
the 4800 (and up) take the larger 110 and 220 ml cartridges which negate the need for a CIS, the machines are much better built than the smaller ones, built to last I suppose you could say, the canned profiles are pretty damn good straight out of the box, the 3rd party profiles are good too, I could go on and on
seriously, I know it looks expensive on day one but trust me it makes up for it in the long run
hope this helps
