Does anyone use the aftermarket inks from Grimco that they are running a special on right now? I have a xc540 and I have to say the 84$ cartridge price is appealing. I have never ran anything other then OEM but always looking to save a buck or two. Don't want to cost myself more in the long run either. I think its made by 20/20 or something like that. Anyone ever ran it? Thanks in advance.
