I avoid using the SKS one, it's steel and not protected by any type of coating. I can see myself nicking the barrel some how.
I got a generic cleaning kit with a small caliber brass rod sections and for larger caliber they are steel coated in rubber. I also have one piece fiberglass rods, which I use more often then the sectionals.
If your going to spend money on a decent kit, look at the OTIS master kit. It's pricey, but from what I've read, it's the "cat's meow". I'm seriously looking into one myself.
