ovrtake,
We had the same problem with GLN Compliance. We ordered the MEL, NEF, and the RVSM books for two new aircraft. We had been using another company. When we finally got the books from GLN they were pretty good, but getting them to return calls was very frustrating. I would not us them again. When I finally was able to get someone to answer the phone I refused to let them put me on hold for fear of getting dropped. Good luck.
