Well, I don't want to spend $1000+ to buy a scanner, so I guess it's either e-bay, or an Epson. I wonder what the quality hit is in using one of the newer ones, like the V500 or V700, as opposed to a dedicated scanner. Since my original post I thought about all the 120 film I have also, and the 4x5s as well.
If the quality hit isn't too bad, I'll go that way, as I can do all 3 formats, If it's a lot worse, I'll probably do an e-bay slide/negative scanner and eventually get the flatbed for the other formats.
Thanks everyone for the advice, and especially the link to the better film holders.
A couple of a350's, an a700 and now an a580, plus even more lenses.
