SQL Server Tools

Does anyone know if there are any SQL server tools that come outside of the SQL Server installation itself and how to obtain them.
I have search Microsoft and other but cannot find a set of tools or utilities to manage SQL server.
A good example would be a utility like SQL Enterprise Manager MSC. This way I can carry it on a CD so when I visit a customer site that has SQL installed, but not the server tools, they would be available.
Thanks,
