I have a Brother MFC that has been working for ~10 years now. No problems using third party toner.
One thing I did notice, though, is that it will start complaining and bugging you about replacing the toner before it actually runs out. There's a well-known way to reset that check, though, allowing you to print until it actually runs out.
