Just wondering. I tried that Walgreen's refill thing, and my printer completely shut down. I wanted to try to avoid the $100 something I'd spend at Best Buy on ink, and found sites selling generic ink online. Has anyone tried them? Do they work? What's the quality like when compared to your regular ink? I'd probably get the expensive color inks from HP, but I figured black is basic and I'd be able to go generic on them without seeing a difference.
