I’m happy with my Brother laser. Can’t comment on their recent models as it’s 10-15 years old! It was about £200 up front and a replacement toner is about £60, but it lasts and lasts rather than inkjet which seemed to need new cartridges every month. No issues with needing internet, and it accepts third party toner fine (though I’ve had quality issues with some brands).

At our place it’s the IT guys trying to tell us to exclude the entire Downloads folder. One of our devs had to put her foot down and say no, we’d do something more sensible/limited instead!
