I use one for my lab/printing service. I don't know that I would recommend one for a single user. They are great printers, but they need to be used and despite what Epson says I would not characterize them as low maintenance. My luck might not be as good as Jack's -- mine clogs frequently, and I use it pretty much every day. Sometimes clogs clear easily and immediately on an auto-nozzle check, so times they take cleaning. Sometimes they just need to sit for awhile. My worst kept me pulling out my hair for about a week. This was caused by a single deflected nozzle that caused banding in every print and did not show up as clogged in the auto nozzle check. The ANC is not foolproof. The problem was barely visible on a nozzle check, even with a strong magnifier, and resisted several cleanings. Finally the last clean before a power clean got it. Epson told me it was because I used non-Epson media (Ilford and Harman papers), and were convinced that it was caused by the paper settings. But their help is quite good, so I don't mean to disparage them.
I do find that I have to scrutinize every single print I make to be certain there is not banding, at least when doing exhibition quality work. If the auto nozzle check fails, it will continue to print (which is strange and a huge waste of paper...it should at least ask you if you want to continue). I also had one brand new Epson cartridge just simply not work. To their credit, Epson sent me a replacement via FedEx overnight to my US address (too bad I am in Iceland...I bought the printer in the states though). Perhaps this is all par for the course for these printers (this is my first wide format printer), but I did not have a single problem with the 3800 I used to use.
When they are not clogged, the print quality is fantastic. Loading is easy, but it does not really like the smallest sized prints when using sheets (A4/8x10)...the borders don't tend to be absolutely perfect all the time. The measurements in the software do not line up exactly with those on the page, so if you need to print exactly to fit a frame or mat etc, you need to print tests and measure first...
It is gigantic and the vacuum is pretty loud when it prints, but if you have already had a printer of this size, you are probably fine with that.
Overall, I would recommend it, but not if you are just occasionally making big prints. Better in that case to pay someone else (like me) to deal with all the headaches. I hear the Canon printers don't give the same headaches (but also don't give the same ultimate quality), but I have not used them....
Bottom line is that the clients love the results, and when it is not making you scream, it is really impressing you with its quality. But if you just want something to turn on and print big with no aggravation, I would look elsewhere.
