PVC will outlast the metal by 20 years, is easier to clean, is not as pretty as the shiny metal (which will rust eventually), and, in powdered form may cause cancer in lab rats.....not sure about the last one, but pvc is a good alternative any way you go, except possibly in a commercial application.

The fumes was a joke to Chandler in response to his powdered rat comment heh. Just ignore it.

As for what makes plastic go bad? Sunlight...over the years. Just being around..basically years down the road if you go to cut it...it may become brittle. But your talking a long ways down the road for that to happen. There really isn't a downside to using plastic. And Chandler's comments in my opinion are right on the money. I'd go plastic all the way.

The worst enemy of pvc is sunlight. Along with electricians with long drill bits.
