Buy another slow 3880 or upgrade? Could use some recommendations please!

Hello all, business is growing and our one 3880 can’t keep up anymore. I’m not sure if we should just pick up another 3880 or upgrade, I’m leaning towards upgrade because we would like to do wider prints in the future and would like something considerably faster than our 3880. I would like to pick something up directly from Epson or a dealer so that I have a warranty and would like it to have one with refillable carts available for it. Does anyone have any suggestions??

Thanks in advance!
