Have you looked at the Penthouse Maker (or Pento Data Integration)? http://kettle.pentaho.org/
we use it to copy and save synchronous systems with different databases, such as mssql ↔ mysql, which you seem to be requesting.
The kettle is even more efficient, which allows you to query ldap databases, direct text files, etc.
its charting tool is similar in appearance to microsoft dts (but more powerful, imho)
