I had an R1800, a good printer for sure. Although it's ink useage was a scandle.
I fitted mine with a CIS system and after a lot of prints...the printer was end of life.
I replaced it with a R2880 which served me well, again i fitted a CIS system to it, but after 2 years I got head clogging issues. The yellow channel completely died on my and I decided to abandon the CIS route and replace it with a R3000, which is easily the best printer I've ever used. I wish i had more money at the time for a R3880, I think it would have served me better, but I wanted the ability to print onto CD's (important for me at the time) and that was the swing vote for me along with the price.
I've been using it with a Marrut / lyson re-fillable cartridge solution and i have to say, the results are fantastic. the best prints I've experianced and easily match the OEM colours. I'm on my third set of inks for it and I've had it now for a year and a half. It's messy to refill the cartridges and clear the chip, but I only have to do this every 3-4 months or so and I do them all in one go. It's a lot more reliable than the CIS systems I've used in the past and the colour vibrancy is the best i've used. It easily matched the Epson colours when profiled. I tend to use semi matt papers, I like the wedding / photographic look, so I was a big fan of the ilford perl papers until that company folded earlier in the year.
I hope this helps!
