You'll want something that ISN'T chrome if you want something that actually works, rather than just looks good. I find the best quality is Grizzly, although it comes at a very high price - i bought a grizzly guard that sold for $1600 - luckily i got it for $250 used. Anything you find at wally-mart type stores is just for look, typically a thin gauge metal with cheap tai. chrome.
For example
A friend bought a cheap $250 (new) push-bar from one of my suppliers and not even 1 year later its begun to rust and peel. The grizzly I had is well over 10 years old and still looks LITERALLY brand new.
