Mr. McMortal,

>The "big three" are ComponentOne, Infragistics, and SyncFusion. I talked to Cathi Gero when I was at Microsoft this week about DataGrids from these vendors (she's checking out integration with MM .NET), and she seems to favor the DataGrid from ComponentOne so far.

Have y'all checked out Spread for WinForms from FarPoint? It is nearing release and looks pretty capable (at least the website has pretty screen shots). :-)
