I bought a used but clean Xerox 6500DN color laser in 2013 for under $200 and never looked back. The black toner has been low for at least two years now. I bought a replacement toner cartridge over a year ago so I would have it ready to install when needed. I'm still waiting to put it in.
The only reason why people stock up on ink in the first place is because those damn inkjets waste about 1/16th of the cartridge every time you turn the stupid things on, shut them off, it rains outside, you flush the toilet, or if it's a Tuesday. Consumers need to dump inkjets altogether unless they need photo-quality prints. Even then, I'm not so sure that I wouldn't just send the images off to a reliable third party for printing.
