We have been using the neat prtable scanner for years as well. Truth be told we would be LOST without it, and would replace it immeeeeeediately if not sooner if it were to die. It paid for itself quickly by not having to pull off the road to find and pay to fax paper work to our carrier that they needed for the load we were on.
Quick tip, I scan any paper work that is going to be emailed in the PDF format so anyone can open and view without having the neat software. Another tip under the "quick scan" there is an option for multi-page scanning, usefull if you plan to keep run paperwork electronicly, it allows you to have it as one file instead of a seperate file for each page.
