I need advice on purchasing a film scanner. I want to keep it under $500CDN. I've been borrowing an HP one that scans at a max of 2400dpi, and have been using the photos for a website and a small publication, and it works decently. If it can scan medium format, it is a bonus. I don't need to scan prints, I have a flatbed scanner. Any reccomendations? I've heard Minolta makes nice ones, and I'm most likely looking to buy off ebay.
