As a small business bootstrapper I was looking for an inexpensive multifunction all in one printer, copier, scanner, fax (actually I wasn't looking to get a fax, but this printer came with it, and it is a good deal).
As you might guess I ended up going with the Brother MFC-420CN. I have owned it for a few weeks, and it is working out great.
I haven't had to use the scanner yet, but the copier and printer work great. My only issue was that I was having trouble printing an envelope, it would smudge ink on it. This wasn't a standard business envelope however, it was for an invitation, and was kind of bulky.
Ink consumption seams to be pretty good, I know some of the comparable printers ship with very small ink cartrages, the adobe one at least.
Overall I would recommend this product for any small business or home office.
