It really depends on whether or not you need to print on roll film. I'm not a full time printer anymore so 17 x 22 sheet fed was great for me. I had repaired my 3000 waaaay too many times and I lost all patience with it! Walked outside and gave it the slam (very satisfying). Thought it was a pretty sharp printer until I purchased my 3880. Now I realize how much the print quality had degraded. I don't print everyday, or even every week, and the 3880 has been much better than the 3000 at not needing cleaning and aggressive maintenance. Ink tanks are not huge, but reasonable. I haven't seen bulk cartridges for the 3880, but Cone Color sells replacement cartridges and ink for the 3880 for less than OEM. Works great with Accurip too.
It was a deal as a refurb from Epson, but the first one did not work and I had to get a second refurb and ship back the first (on Epsons dime). So I can see the value in a new Epson rather than a refurb if you have production demands.
I see that the 3880, while still available, is being discontinued for the P800 which also handles rolls. Have not heard anything about the printer as far as reliability (or how well it handles roll film), but BH photo has a rebate until dec 31st which makes it $845 new. I have no idea if any rips support it yet.
