You can get Lectora without all these addons – it’s called Lectora Publisher. It’s still very expensive for what you get though (in comparison to the leading competitor). Lectora Inspire is the package that contains all of these extras.
I agree that Review Link is great though I have had quite a few issues with it of late.
Camtasia and SnagIt are phenomenal but I have them separately anyway.
I also have no real interest in Branch Track or eLearning Brother’s assets.
