D7000:Flashing Info Light with Battery Pack

I've looked at user reviews/comments on every 3rd-party grip for the D7000 that I could find. Unfortunately, every one had some kind of problem, from uncertain contacts to reversed dials to slow shutter response.    So I'm simply trying to round up the $$ for the Nikon one. It seems the only way to have one that is fully functional and dependable in the longer run.
