OK, so creating this thread because as much as I love Nikon first party stuff I have come to notice that many 3rd party manufacturers are filling in the gaps nicely. I currently use a 3rd party grip on both my D&50 and my D7200, and although they do not feel as solid as the Nikon branded grips I have had less issue and saved more money! (I tested out the Nikon branded grip on my D7200 and had some serious battery drain issues and blinking green light issues. Problems I do not have with the 3rd party grip)
As an added bonus both of the grips come with wireless remote shutter triggers!
For the D7200 I have this one in particular http://smile.amazon.com ...=oh_aui_search_detailpage
The only issue I have with it other than the shutter feel being slightly different and there being a slight bit of flex between the grip and body. Otherwise it has saved a pretty dime works wonderfully and gives me remote shutter as well all in one package!
I have the same to say about the MK-DR750 except this one has never displayed any flex between the grip and the body in the use I have put it through.
