The quickest way to get the general shape would be with the "Create Polygon" tool. You can then use the "split polygon" tool to "connect the dots". You can then simply extrude it to desired thickness and convert to a sub-d or otherwise leave it as is. You'd probably have to make it a "high-poly" object if you left it as a polygon, but in the end it all depends on the needs of the production.

Just another suggestion to add to the list already given! :-)
