I have not really used stereo to build in probably 3-4 years. The majority of the users of my facility on the other hand really want stereo. Usually in the initial and final stages of building and analysis. It is becoming harder to maintain stereo systems overall. You are tied in to a very limited number of graphics cards and as seen on the BB setup of the drivers/libraries can sometimes lead to the urge to pitch the systems out of highest window possible. It would be nice to have some sort of 'standard' 3D system for crystallography, but with the rapid change in computers and graphics hardware it probably is not a really viable possibility. We are currently looking to upgrade our systems and the biggest problems I have encountered in building a system is the on the graphics end. Just my 1/2 a cent worth.
