I had a big long post prepared about it but it really boils down to this for me. I have a 600DPI flatbed scanner. It does a good job. It takes forever to scan a roll. It's a tedious process to position each strip. The local lab is way too expensive ($3/frame). I'm saving my pennies for a dedicated film scanner that will scan contiguous rolls.
