Discusses the cost not just in dollars but in terms of team pain. Most places do have less than perfect processes for developing and testing code. Does that mean TFS is the only game in town?

Nothing wrong with using Bugzilla or Mantis for Project Management. Even Jira is cheaper.

Also, CVS and Sub version are not perfect but tested in house.

Now I am up at 2 AM looking at posts about TFS costing $1,500 per seat some how.
