Since you are saying that you are looking for an office scanner with a ADF (Auto Document Feeder) how about the Panasonic KX-MB781 Multifunction Device.

I bought one for my mom who is "technically challenged" and she has had no problem.

Besides being a decent scanner that you can send to e-mail, the machine works as a laser printer, stand alone fax machine and copier. It also has Network Support so if you have more than one computer in your office the other person can work on it too.

Panasonic sells this device for $200 but a search should find you a cheaper price with free shipping.

Check out the user reviews that are on Amazon, Buy.com and other sites. This is a great machine for the price.
