Wow, VueScan! A blast from the past. I used it 15 years ago. Glad to see it's still around, maintained by the one guy (and now him and his son according to the website). I'm definitely going to buy a license now ($99) and ditch the 32-bit manufacturer's software.

Software like VueScan and USB Overdrive (just bought a license for that too $20) deserve to be in some sort of Apple Hall of Fame.
