drupal modules

While working on a business directory today, I came to a stark conclusion - The state of GIS (Geographic Information Systems) in Drupal 6 is in a sorry, sorry state - despite being very important to a lot of people. I had implemented similar projects in Drupal 5 before without difficulties using the Location module, so I was expecting this to be a piece of cake. Unfortunately this was far from the case, because every GIS related module out there (as of today) is either lacking necessary (in my opinion) features, or is broken in some major way.
