I'd move up a notch and get an Epson 3800 or 3880 refurb and if you were already using the canned profiles, continue to do so.
The cost difference between a 2400/2800 series printer and the 3800/3880 would be that after paid for a similar quantity of ink, you almost get the printer for free, you get a newer print engine, faster production and the ability to print up to 17x22 all in the same package, and as a bonus, your cost per cc of ink will be 20-40% less...
The refurbs come with a full warranty so the clock starts anew.
If you are by a large city, you may be able to find a place for repair. Next best thing is to go to eBay and find the same printer and hope it's in good shape and doesn't get jostled too badly in shipping to you.
To find a refurb, start at Epson's website.
I always recommend to my clients that it's usually money ahead to go to newer generations of printers/computers since in the long run they'll be money, time and frustration ahead for not much more up front. Since this seems to be a business for you, it's even better advice to move ahead, cry once and keep things moving.
