Depends on how busy you plan to be. The Brother MFC L6800DW is a fast printer with dual tray capability, scans directly to an email address or to USB, accepts prints from your smartphone, copies as needed, and has a 520 page paper capacity. It is not, however, cheap - Amazon has it at $589.00. However, it is a reliable multi-function machine that quickly produces excellent quality prints.
No, I do not work for Brother. After many years running a small business, I find that they offer a good value for the dollar.
