I am considering getting VSS and was wondering what were people's thoughts on it in particular?
Microsoft is pushing Team Foundation Server (TFS) as a replacement for VSS. VSS does offer the simplicity of a file based system, but you will spend a good amount of time repairing the database every so often. TFS is a much more reliable server based system. Visual Studio 2010 comes with a client license and a up to 5 person server license of TFS. You are better off putting your money there.
TFS Costs.
Because the question is a license/price issue, you can call 1-800-426-9400, Monday through Friday, 6:00 A.M. to 6:00 P.M. (Pacific Time) to speak directly to a Microsoft licensing specialist, and you can get more detail information from there.
