Sorry, I disagree. I recently purchased a SS4000 and, trust me, getting such a great scanner for $450 WAS NOT A MISTAKE!!! I don't have a ton of old dusty film and I find that scanning new slides/negs is very easy. On average I spend about 10 seconds using a StaticMaster brush and maybe 2-3 minutes de-spotting in Photoshop. Which is nothing compared to the time I spend tweaking color, contrast etc.
