I thank you for assisting me, and if other people who read this thread feel like they do not want to assist me, then they don't have to, but I appreciate your help!
What I am suggesting is the creation of objects for use in SL not as a professional business, but because my parents (who are in their 80's) have "found" second life and enjoy it tremendously. Though I have and use scanners in my professional life, my interest in SL is to make things that will delight not only my parents, but others as well. I felt it appropriate to mention the cost of the scanner because the less expensive scanners (Microsoft Kinect and the like) produce one quality of mesh, and the scanners I use produce another quality of mesh. I wanted to save time by mentioning the price of the scanner to move the discussion away from, "Oh, a scanner is not the best tool for getting detail..."...because most people assume that the discussion is about the less expensive scanners, and their capabilities.
I will run the command you said and look around, but I am not sure if that will help me....if I modeled something by hand, I would try to save the most time as possible while still getting the best result (the "hours" comment you said in your post)....but the scanners have no such requirement...and that is why I was seeking a guide to maximum / minimum limits to mesh detail to help me see if the scanners can produce something nice when the meshes are simplified to a specific number/threshold.
