Choosing a scanner for desktop publishing, newsletter

[CarlB]

I am working on school presentation where I compare and recommend three scanners. The scanner will be used for publishing a newsletter at the Human Society. This is a hypothetical situation.

What factors are important to desktop publishing when buying a scanner and why?

Here is what I thought were important factors
-DPI (optical)
-Ability to scan legal documents
-PPM
-Color depth



I was given three scanners to chose from and sadly they offer most of the same specifications. Which would you choose for a newsletter and why? Cost is not a factor.

Epson V700: http://www.bestbuy.com/site/olspage....=1158322692617
HP 8270: http://www.bestbuy.com/site/olspage....=1218009770391
HP 8300: http://www.bestbuy.com/site/olspage....=1218009780506

-The Epson will not scan a legal document
-They all are capable of 4800DPI optical
-The 8270 has the same specs as the 8300, but has a document loader

This presentation may depend on reliability and brand preference for the recommendation considering how similar the models are.
