We have been buying from V4Ink for a long time. These are the best 3rd party toner suppliers we've come across (not the absolute BEST, but out of the ones we've tried, V4Ink has worked great for us). Cartridges interact correctly with printers. It had no weird spots or streaks and is quite long lasting. For the price, I don't think it's easy to beat.
