I'm with UALOneKPlus. I've been using NR for 2 years now, upgrading to version 3. The scanner is very versatile and, whilst there are some limitations with the software (handling european date formats for example) the scanning and processing is quick and pretty accurate.
The two real pluses for me are the searchable archive of receipts - find that proof of purchase from years ago - and the ability to export data as a QIF file for Quicken. I run all my accounts, taxes and expenses through Quicken and the ability to enter accurate data quickly saves hours of typing and many errors.
It's very portable too, I never travel without it and return home with all my expenses organized and categorized and ready to transfer to Quicken. I'm looking forward to the forthcoming Version 4, with an even better scanner.
