Definitely go with the heavy truck style chains like said, easy to rebuild! Even with the cam locks it's a good idea to get bungees for them just incase they break, so they don't go whipping around and do some serious damage!
I've seen cheap chains break and wipe out brake lines! Not good. Another thing to keep in the back of your mind is if you have to put them on, to drive about 30 to 40 feet and then retighten them.
