all the ones on e bay are fine Mieke is a good brand ..buy cheap drop it replace no problem .. the cheap EN EL 14 for the P7000 at $10 work fine IF you fit the original first and then always keep one battery in the camera..either does not matter. D3100 grip also fits D3200

Try this one. I just got the Vello grip for the D5100 and like it. I also ordered an aftermarket battery for $7, which should work just fine as long as a real Nikon battery is also present in the grip.
The Vello grips are more expensive, but the color, texture, and rubber grip on mine matches my camera perfectly.
