UPS brought my new 7100 today and it looks like I need a battery grip for vertical holding and the second battery for videos. So I looked and there are a bunch of them. Vivitar, Pro Grip, XIT, Meike and Neewer for around $40. I have two batteries so just need the grip. Then there are Nikons for $125 - $230. Why is there such a difference and is there any of the $40 ones I should stay away from. I would like to just order one but want your advice as it has been great so far.

Thanks

I am looking to buy a hard case for my photography equipment.I am leaning towards a pelican. I have out grown my back packs and need a safe and secure case for when we take out the RV or go on vacations. I will keep my backpacks for when I go hiking or do a specific shoot to carry only what I need. After the holidays I wll be buying the Canon 6d along with some lenses to finish out my lens collection.I also read a post from mt shooter that the new sigma 150 to 600 would be out early 2015 for the consumer. I may wait until then to spend some cash :-D .This is the pelican I am thinking of getting. Pelican - 1564 Waterproof 1560 Case with Dividers (Desert Tan) Any other suggestions would be helpful.

This is a relisting. The original buyer couldn't come up with the money.

Sigma DG 150-500mm, 1:5-6.3 APO HSM (Hyper Sonic Motor for Auto Focus) lens. Optical Stabilizer. Nikon mount.

Excellent condition! No dings, scratches, or scuffs. Optics are perfect. Comes with padded carring case, both front and back lens covers, Hood, 86mm UV/Haze filter and original box and manual.

Attached is a picture of the lens and a picture of an egret taken at 500mm. The lens is very sharp all the way out to 500mm.

Price: $700 plus $25 for shipping and insurance within conus. Paypal is great or if you can wait, a money order is fine. PM if interested.
