The advantage of having the option to buy a cdrom with the plans is that it eliminates the shipping problems which sometimes happens when shipping plans in paper tubes. Some postal services around the world seems to handle it better than others, but I can tell you that I have had 3 different shipments of plans (all of them in really sturdy tubes and/or boxes) all being destroyed almost completely. It must happen at my side since the guys keep telling me they send plans all over the world with no problems, but I seem to get just about everything damaged or destroyed. Then when I bought the Insight plans from Mark Hunt he offered me the files to have them printed locally and it worked out great. Thanks Mark!
