How many companies out there make greyscale inks (meaning all color cartridges are replaced with a grey toned ink of varying strength)? I know inksupply makes one called UT3D and maybe an eboni version, but I am not certain which other companies (budget or named brand) makes these greyscale inks for the r2400. Please list as many as known as I want to try a few to see which I am happiest with.
On a separate note, does anyone know of a company that makes a CIS for the HP stylus 8750 13x19 inkjet printer?
