I'm attempting to ask an honest question, while staying within the Forum Guidelines, therefore I won't say what resource I'm speaking of or link to where it's located at. With that said, I found a particular resource that I am interested in, it is NOT a PBB, but designed for Libronix specifically by a professional company. The price difference of the resource is $96. Is there a reason why the one advertised by Logos is so much more expensive? Should I just buy the cheaper version, or is there something unique by the one made by Logos?
