Although this software is wonderful, don't even consider buying it if you want to manage a scanner over a network (local or otherwise). Hamrick has said they don't plan to support networked scanners. That's sad really, since networked scanners are more and more common and that feature really should be part of any Pro software.

I've used the software for years to manage various scanners, but the software is useless on my networked Brother color laser all-in-one.

Still, if you don't have any networked scanners, VueScan is a solid piece of work that still needs some UI usability enhancements (though it has improved over the years).
