I have a cable type on my tub. I'm not sure of the manufacturer, but I think it was something like Mountain. The working parts are SS or chrome plated brass, but the hiddend parts of the overflow and rest is plastic (some brands are all brass). It works well, but has one annoyance that I've not resolved - the suction when draining sucks it down. You either have to hold the knob, or pull the stopper out (it's not attached, it just sits on the level that pushes it up - gravity or in my case suction pulls it down, or you turn the knob). One of these days, I may get in there and see if there is a screw in the pivot point or something I can tightet, squeeze, or bend to provide a little more resistance on it.
