I didn't see where you mentioned your dish.
You might want to toss that out for comment, as well.
Shipping for 30, 33, and 36" dishes is about the same.
But bigger ones gets outrageous to ship.
Pricing between these sizes isn't much of a step.
Bigger being better, I think you can see where this is going.
When I bought my hardware, I figured the extra $10-20 spent for some better part, way offset having to throw away an "inexpensive" one later, and buy the better one.
