First, a pretty good, reasonably hi-res dev/scan at my local family-owned lab runs $11 and takes very little of my time, except for final adjustments of the resulting files. You might consider that, and try to find a lab that will do it that cheaply, for your first batch of 10 rolls.
If you really want to scan film in the long run, I have the Plustek 7300 and like it just fine. Very good value for the money. I've used both the bundled SilverFast and VueScan software. Both are clunky as hell, for different reasons, but they get the job done. Lately I'm back to using SilverFast, as I seem to have better results with troubled negatives (say, really thick ones). Not sure why the software should matter, as both packages do multi-exposure, but it does make a difference. I wish PlusTek would come out with a 120 film scanner. We can always dream.
I must say, every time I develop a roll of film and then scan it, I laugh at the common assertion that film "takes less time" than digital. It certainly takes a
lot of
my time to process film, but I mostly enjoy the process, so it's OK, and it's almost free after the initial investments.
Here's a link to some of my negs scanned with the 7300 (and plenty of PP by me):
