I used Suburban Photo on the recommendation of my wedding photographer. I took in negatives that I wanted to make reprints of. The staff was very helpful and gave me lots of options on how the pictures could be reprinted. Their prices are more than drug stores, but the quality shows. Its also less than getting reprints through a photographer.
I had 50 prints made and they were able to have them done in 2 days. I was expecting it to take much longer. Every print came out beautifully.
