We are in the process of rewriting our app using C# / Silverlight, and I'm researching .NET-based reporting engines to incorporate that support a Silverlight report preview control. Based on a cursory search, I came up with a short-list of products to look at more deeply:

Xtra Reports (DevExpress)
NetAdvantage Reporting (Infragistics)
Report Sharp-Shooter (Perpetuum)
ActiveReports (GrapeCity)
Stimulsoft Reports
Telerik Reporting

I was wondering if anyone knew of any other products that might be worthwhile for me to examine, or any to stay away from.

Thanks.
