Have an HP 4000 laser that takes cartridge C4127X. It's an older printer so the local stores don't stock it. I have bought old sealed HP cartridges with good luck in the past but the last one has some streaking. So wondering if I can avoid the normal $150 - $180 price tag and get decent prints. I see lots of places advertising cheap ones but have been hesitant... Any recommendations for good places that offer a warranty if things don't work well?
