Now that my dad is aware of the existence of color laser printers, he has decreed that that's what he wants.

I'm pretty decided on the second-to-top Brother all in one. We've had good experiences withthem in the past. Only other feature I'd like, until dad makes a move on Extreme Fax, is the ability for the FAX part of the machine to save incoming faxes to FTP or network share, to be printed if and when we want. Unfortunately, a whitelist isn't feasible at a dental office. They receive lots of faxes from different numbers, and lots more junk faxes.
