I agree with SaveKodak--get the newest model with a warranty. I've never had great luck with refurbished anything.
I don't do commercial work so I'm only making prints to satisfy myself. But I am a pretty tough critic. I've been using an R3000 for about 5 years. My printing schedule varies from several daily to nothing for 3-4 weeks at a time. Sizes 6x9" and 12x18". I've only had to do cleaning cycles a few times with mine. It just keeps on cranking out beautiful prints. But I know Epson printers have the reputation for clogged nozzles that eventually kill the machines.
I only use matte finish rag papers (therefore, the R3000 is only printing with the matte black ink cartridge). I never use any other type of paper at all. While I've only been printing B&W most recently, I also follow Ctein's advice on color management when color printing--let the Epson printer's software manage the color and forget about custom and downloaded profiles. Since I started doing that, I've had less frustration, fewer reprints and I'm getting better looking prints.
