you are correct on two points...there is no CIS available for this printer because of the design and ink acquisition. Second...running costs cannot be given as it is entirely dependent on the size of image printed, the amount of each color in the design. It will comparable to ink cost, running cost for an Epson unit with sublimation inks. I have been using a Ricoh GX7000 for 3 years and would not go back to Epson because I have no clogging issues...I know there have been threads that the GX7000 has had issues, but so far for me it has been a workhorse
