Thank you for the nice words about the updated versions of our controls (part of the RadControls for ASP.NET AJAX suite) and for the improved installation experience we shipped with this release. We are constantly working on enriching the capabilities of our controls and improving their performance with every subsequent release and we are pleased that you see the results and are content with them.
Concerning your questions about RadRotator:
It is the last remaining control from the RadControls for ASP.NET suite which still does not have counterpart in the RadControls for ASP.NET AJAX suite (formerly known as Prometheus). However, you may be happy to know that we plan to migrate RadRotator for the Q2 2008 release, expected in the middle of July.
