We own two Brothers, one of which prints ~500 sheets/month for the past 3 years (model HLL2395DW). The one time we had a problem (unrecognized Brother drum or toner unit bought through Staples) support helped to diagnose and fix the problem.
Only minor gripe is the process for getting a return label for recycling toner which requires reading a minuscule serial number to enter into a web form.
