And so almost half a year has passed and I ended up buying an Epson Photo P50 from inksystem.com with a ciss already installed. I thought that Epson R2880 would be a little bit too expensive for my first Epson printer. First I have to "get to know" them.
It has 6 colors CMYK,LM,LC and so far I've made about 500 color prints. Working very stable. No hiccups, no clogs, nothing. Everyday I make a nozzle check before starting my prints and so far I am more than happy with the results. If this printer manages to give me 4000 prints without too much trouble - then this printer will be considered as a real success to me.
When you buy a printer with ciss from inksystem they give you a 1 year warranty for the whole package so I figured it was a great deal for me because I get a warranty from someone who knows that I'm using a ciss with non original ink and isn't going to complain about it if something goes wrong with my printer and I need it fixed. I'm planning on using only their ink as it costs the same as my previous ink for Canons and it guarantees me that I will have a working printer for a whole year (I used to change my Canons every 2-3 months). Even if it breaks - they'll fix it.
Print quality - on best quality settings I cannot distinguish any quality difference between Canon IP4850 and Epson P50. They are both great. Normal quality is a little low for very small objects (like very small text).
Print speed - normal quality is faster than Canon. Takes less than 2 minutes for full A4 print, whereas Canon took ~2min. On best quality Canon is about 20secs faster. Epson prints full A4 in about 4min 20sec. But since normal quality is sufficient for most of my prints, it's a "win" situation.
Color output - it is better than what I had with my non-original ink Canon setups before. Blues and Greys are no longer so green-ish. But it is still far from perfect and I am planning on ordering a profiling service for my ink and paper.
BUT there is nothing perfect in this world. And I have 2 annoying problems with this Epson

the first is that you cannot completely disable ink monitor as you can on Canon. If my print is made of mostly 1 color and it is quite saturated, I can make only about 20-25 prints before ink monitor tells me that I've run out of ink and need to reset the chips. Canon didn't have such a problem. And the second is that Epson does not finish the print before alerting about an empty cartridge. My Canons ALWAYS waited till the sheet is completed printing and only then they gave out an error. Epson stops in the middle of printing so I always waste a sheet of my photo paper when I have to reset the chips.
All in all I am very very very happy with this printer so far. Mainly because it doesn't clog as much as my previous Canons did. Actually it hasn't clogged yet at all. I really hope it stays that way until I make my 4000th print.
I am very thankful for all of you, who suggested using an Epson with a ciss instead of a Canon. You have saved me a lot of time, frustration and nerves. And probably money too
