Some pluses for Vuescan
When your scanner vendor no longer updates the driver, Vuescan lets you go on using it (and my blessings on Mr Hamrick for enabling me to use a film scanner that no-one wants me to be able to use!).
If you ever get another scanner, you won't have to pay for more scanning software.
You'll never have to pay for scanning software upgrades.
Scanning is a bit of a black art
You'll need to use your grey cells on either Silverfast or Vuescan - I learned by playing around with all the options to see what effect they have.
BTW, because I only ever want to physically scan once, I also save the unprocessed version ("raw"). That way, if/when my processing skills improve and/or the post-processing software improves, I can always go back and try again. I'm using ColorPerfect/Photoshop and Lightroom to integrate with my DSLR image handling.
