I love the fact that they just print too! No more "inkjet cleaning test prints", I've saved so much time, money, and frustrating switching to a brother black and white laser printer... For the average (?) "I just need to print official documents" kind of person, it's a great buy.
I have a dell 1350cnw which was made by Brother. Bought in 2010, survived an international house move. Still works great (only downside is the drivers are 32bit so I have to keep an old computer around to act as a printer share on my network!)
