Ah! I disagree .... I'd recommend the PRO version over the PHOTO versions, as it comes with Monaco EZ Color calibration software, an IT8 print target and an IT8 transparency target. Essential for colour management. You really cannot calibrate the scanner properly with the Photo versions. It's one thing to have scanning software, it's another to have scanning AND calibration software. And it's only $100 more which is a steal.
With the Monaco Ez Color software, you will also have the ability to calibrate your monitor and printer as well.
You can buy all models directly online from Epson's online store.
