For small to medium sized organisations, Canon's DR-C125 is a very competitive package. It combines everything required for high-quality document scanning and distribution in a size that will squeeze into the most space-challenged office, and at a price that will fit in even the tightest budget. It is also compatible with PC and Mac environments with a great software suite included.
