I'm so tired of looking . . .

I don't have the greatest research skills in the world and I've spent hours looking for a home office multifunction unit (printer, copier, scanner, fax) that includes, at a minimum, these functions:

1) ADF (automatic document feeder);
2) single-pass, duplex scanning (from the ADF);
3) color scanning;
4) wireless printing that includes Apple AirPrint; and
5) cost under $500.

Everything I have found seems to be missing at least one of these features. Can anyone help me locate an MFC...
