I paid $149 for my Black Powder-coated Nerf Bars from Ebay. I probably got the majority of my mods from Ebay so I highly recommend shopping there. Also, I was going for the understated look which is the reason I got the Black. The good thing in my case is that the Black Powder-coated stuff is usually cheaper. I am not really into the chrome/stainless steel look but I think they look good on the Rogue none the less. As for installation, the cost was free and it probably took 30 minutes on the driver side and 15 minutes to install on the passenger side once you know what to do and interpret your directions. You sacrifice a short afternoon at the most. On my set you had to actually drill ONE small hole for a little attaching support bolt, WHICH I skipped since it was REALLY solid with the present set-up and the remaining bolts I used. I really didn't think I needed it since I was supplied with these really big supports & sturdy attachments for the frame where I knew it was immoveable no matter with or without this extra screw.
As for Black-Coated or Chrome/Stainless Steel look, buy what makes you happy and also what you would think would compliment your color too if you want. I chose Black
just in case it does rust for some reason and I can use some rust convertor which ends up in a Black Primer. Plus, I could remove it and repaint it Black if I ever needed too. Well thats how I thought when contemplating the color.
My opinion of the benefits at least FOR ME, it gives you something to rest your foot while door is open. It helps shorter passengers and little children get into my vehicle. Since I am short, it helps me wipe my windshield and clean the top of my roof. It makes my CUV look more rugged and less like a mommy suv at the groceries. ( no offense to mom-mobiles )
Moreover, you need to ask yourself if your more prone to accidents in your environment since some have speculated on a higher chance of vehicle frame damage. Personally, if I ever get in an accident it is usually once every 20 years luckily for me. So ask yourself if your benefits outweigh your risks.

I think it is an acquired taste, for example I believe I am the only one in this forum who has Bullbars and you know how many Nissan Roguers are on here for the past 2-3 years?
Anyways, here's pictures of some Stainless-steel tubes all-around, actually the opposite of my personal Rogue set-up.
