I have had a 2200, 2400, 2880 and now 3880. bought the 2400 on eBay and had no problem. the 2200, 2400, and 2880 will at some point say they have end of life problem. Basically is that the waste ink pads are full and need replacement..... by a service shop. you can reset it, probably once but eventually you will have an overflow onto your table. Possibly you can install a waste ink container. cost of ink is a factor for sure. Depending on what you are doing there are some decent third party inks. Service centre repairs can be expensive, especially if looking t two way shipping.
Finally I bought the 3880, refurbished and directly from Epson. With rebates, selling my 2880 ( with the purchase store's warrantee and full disclosure re ink story) I came out almost even with a great printer and 17 inch wide. Waste ink is not a problem as the container can be replaced or even renewed if one wishes. I also opted to sell the full Epson cartridges, get refillable cartridges and have been more than happy using bulk ink from Jon Cone's inkjetmall.com in Vermont. Superb ink and can use same profiles as Epson inks. Worth checking out from a technical point. Also excellent service. Absolute minimum ( virtually none) clogs.
Used does save money, but MAKE SURE it works and what to look out for. Check out the refurbished at Epson.
Best of luck.
