WPF DataGrid CTP Available!

I picked this one up via Rob Relyea (of the WPF Team), the long awaited and much requested DataGrid for WPF is available on CodePlex. For more information (including a screenshot), Vincent Sibal has a detailed 'how to use it' post

Requires .NET 3.5 SP1 to run, and it'll eventually will make its way into the WPF core libraries (I think?). Out of band releases are nice.
