In my humble opinion, stay away from the extruded parts whenever possible. I purchased a beltline from ptwerks and it wasn't up to the standards I had hoped for. It is exactly what it says it is - chromed plastic. Same for their grill. So, I purchased a Stull billet grill and Stull beltline. Very satisfied. You definitely get what you pay for. I'm going with polished billet or polished stainless to stay away from extruded. If that's all that's left, I'll get the plastic, but again, you will get what you pay for.
