Best Aftermarket Batteries And Battery Grip For D3200?

I have large hands and would like to add a battery grip to my D3200 to add to it's size a bit. Also, the 1030MAH stock battery is pretty low capacity, I assume there is not a genuine Nikon upgrade battery available, but I have seen aftermarket batteries rated up to 2700MAH ( Zeikos 2700mAh En EL14 Battery for Nikon Coolpix D5100 D3100 D3200 P7100 P7000 | eBay ). Any thoughts from anyone that has used any aftermarket batteries, or opinions on battery grips?

I've had no problems with aftermarket batteries for years. I also like grips and have one on my D700 and D300 not so much for the
extra battery but for the size and being able to shoot both horizontal and vertical.

yes,, I have bought aftermarker batteries for my D700, and no issues, seemed to hold a charge at or close to the stock batteries.

Personally, I swear by Eneloop batteries. I'm talking about the AA kind, not the stock Nikon camera type batteries. I use the Eneloops for my flash, and they are awesome!

If the ones that I say are actually 2700 MAH, that would be a huge jump over the stock 1030MAH, and expecially if you were using 2!
