I'm about to start my first SilverLight 3.0 application and want to settle on a controls library before I go too far. I need various things like menus, graphs and gauges. I'm not interested in open source because I want tech. support services and want robustness. I am considering Infragistics and ComponentOne.
Can anyone suggest others for me to investigate? Price is not as important as function. I've seen a really cool menu demo on ComponentOne: the Amazon.com demo.
If you have a preference, I'd love to hear why.
