Best Practices when Implementing IModelBinder

I'm looking for a set of best practices to use when implementing IModelBinder.

I've read three different MVC books and each one does some slightly different stuff in their implementations without any real explanation.

  • The Hanselman, Haack, Guthrie, Conery book doesn't even mention IModelBinder
  • Palermo recommends extending DefaultModelBinder rather than direct implementation of IModelBinder, but I don't really see how to leverage the benefits
  • Sanderson mentions updating existing Model instances, as well as calling ModelState.SetModelValue() to follow convention.

I just want to make sure that my model binders are following conventions, and that I properly understand the entire ModelBindingContext.

Any tips, tricks, GOOD tutorials to recommend?
