The ability to download and install the free version of InstallShield Limited Edition is included with Visual Studio. This is basically the same as the VS Setup Project was able to do this, if you were happy with it, you should be happy with it and in a better position from the installation perspective and the perspective of the upgrade path.
If you decide to upgrade, usually Professional is enough. There is also Windows Installer XML, and in the past I wrote blogs about strategies for creating a limited-edition project to “increase the installation package” using WiX federation modules. This allows InstallShield LE to expand its workload in various ways.
