I've used a few online companies for scanning and digmypics is by far the one I love the most. My pictures and negatives come back well packed and the scans are awesome. Other places have torn some of my pictures, lost one or two, negative scans are backwards, some had fingerprints scanned on them, and you can tell the scan processing at some places are automated because some of the pictures are just so off that no human would have let them pass.
I've used digmypics before and I'll use them again for my large format wedding negatives in the future. I'll only trust digmypics with my wedding negatives, except I'm waiting for the prices to go down. Large format negative scans are expensive but I will not trust those memories to any other cheaper place!
