Your claim is a little bizarre and is not one that I concur with based on my personal observations. I am not sure why you don't acknowledge the simple truth that MBF is used far more widely than the other systems. Hokie, from your other posts I can see that you may not be "unbiased" in your perceptions since you stated that you used to work for Visiopharm. So, I am guessing that you have a competitive axe to grind.
For the information of others who may read this, I just came back from the Society for Neuroscience meeting where I looked at dozens of posters that used stereology. From my count of the posters I observed, over 80 used the Stereo Investgator system. 5 used Stereologer. 7 used CAST (one was by Visiopharm themselves).
As I have mentioned in one of my other posts here, I am a very happy MBF customer. Also, I have a number of colleagues who are very pleased with Stereo Investigator. When I visited the MBF booth at SfN, I found that this is common among other users. I can't recommend the system highly enough.
FYI, I also visited the Visiopharm, ExploraNova, 3i and Bioquant booths where I received demonstrations of their latest software and spoke with their representatives. My evaluation is that MBF is by far the best system out there.
