Conclusion: The Canon CanoScan 3000ex offers basic scanning at up to 1,200 pixels per inch (ppi) optical resolution, with credible scan quality and performance. Its relatively low ratings for photos and OCR reflect a lack of such niceties as an ADF or digital removal of scratches and dust, but for 50 bucks we won't complain too much.
Pros: Low price. Reasonably good scans for photos. Offers both a simple interface for beginners and an advanced interface for better control.
Cons: No feature for removing scratches or dust specks. No feature for restoring colors in faded photos.
