+2 for VueScan. I have a Nikon Coolscan V ED, which I used for a couple of years under XP Pro, but when I built a new pc using Vista 64, I found that neither my Nikon film scanner NOR my Epson 3200 flatbed scanner was supported. I thought I'd have to spend mega $ on something like Silverfast's VERY GOOD software - and get a copy for each scanner. Not worth it.
I decided to check out VueScan and found that ONE copy worked for both scanners! And it works very well - better than the original software, certainly, but also, it seems to me, on par at least with Silverfast's software. And for hundreds less.
Also +2 on the time to scan the film/slides. Scanning slides, to me, is easier because you have the actual slide there to tell what the color should be. With negative film, you're guessing. Silverfast let you select from different film types (e.g., Velvia) and it got you close, but it was still hard to get things right.Sometimes it seemed impossible to get it right, but that was a few versions of Photoshop ago.
A real positive for scanning your own slides is that you can correct the color shifts in old slides. I have LOTS of old slides that have shifted to reddish - Silverfast AND Vuescan do a great job of bringing back the correct color. I doubt that a high volume lab will take the time to color correct slides for you. Old color negatives MAY have color shift issues (not really sure about this).
