opinion-please read all

I think if someone knows that the part is incorrectly identified or if an assembly is incomplete they should speak up and ask for a clarification. Give the original poster a chance to correct their apparent mistake or give more detail to substantiate their prior post.
Posts that insult or call the anyone names are not warranted.
Value of an item is in the mind of the seller and in the eye of the potential buyer. In the end the value of an item is the money the buyer needs to give the seller in order to get them to hand over the item. If it's priced wrong, it won't sell. It's that simple.

Opinions are worth what you pay for them.

People who get paid for their opinions are either consultants or work for news outlets.
