For a little more than one of those, you could get a V18 combo kit on Amazon. $349 with Circ/Flashlight and Sawzall.
I have been very satisfied with my Milwaukee V18 line. It's not the new M18 line, but I really don't know the difference. I know the batteries are not interchangable. You can still buy a bunch of V18 bare tools to add to the kit. The M18 you are looking at has a much broader range of available tools, though. So it depends on how much you plan on expanding the kit in the future.
You can't go wrong with Bosch either, though. Amazon has the 36V Litheon hammer drill with two batteries on sale for $169.99 here if you do a search.
