I've had terrible experience with "aftermarket ink cartridges" that leaked and ruined 2 Epson printers. Not to comfortable with the "compatible" products. I ONLY buy genuine Canon for my ink jet...but, it's one of the Pixma units that has "chipped" cartridges and so far, the compatible cartridges seem to be hit or miss for those. MOST don't work regardless of the "re-chipping" instructions.
I DO need a good quality toner cartridge for my Canon laser printer. I'm tired of paying $80-$90 for those, BUT, because of my bad experience with compatible ink jets, I'm leery of buying the toner carts...anyone have a GOOD toner cartridge seller? (I really don't want to fuck up this printer.)
