i use an epson v500, it was less than 200$ and come’s with software that works fine. i scan my negatives with epson scan and edit with photoshop.. silverfast has a nice setup and some cool negative presets, but if you’re on a budget I wouldn’t worry about getting other software.
the only bad thing about the v500 is that the negative tray is small.. after each frame you scan you’ve got to open the scanner and tray to slide the negatives up. but i’d still buy it.
