Plastic idler pulley, does anyone make a aluminum or steel one?

My plastic grooved idler pulley bearing finally gave out and I am wondering if anyone makes a billet aluminum one or a steel one? The entire outer portion of the pulley is plastic and the one O'Reillys has is plastic also. I would much rather have one made of metal. For reference this is the one on the left hand side of the engine with the grooves in it.

Thanks

Beuler Beuler anyone?

Are you talking about your idler or your tensioner pulley? I'm pretty sure the idler is metal. The tensioner is plastic I think.

Its the tensioner pulley. I found a company but they are in Australia. NuLine
