Just completed my second old slides scan project. First involved roughly 2000 slides, the second was 1180 slides including some non-standard sizes and resolution requirements.
DigMyPics handled both projects very well with care and precision and in a timely fashion considering the numbers of slides involved. Received the original slides back and downloaded the digital files with no problem. Their website ordering process is very easy to navigate and the phone support was excellent.
I highly recommend their service.
