I think you have summed it up very nicely.
After reading through this thread what really stood out for me is that there seems to be a tendency to associate the word "cheap" with the idea that it means poor quality.
It should NOT.
Cheap is a relative term... it only has meaning as it relates to the price of something else you compare it to. A $700 rifle is NOT "cheap" in relation to a $5.99 happy meal... but it is "cheaper" than a $1,500 rifle. Cheap should simply refer to the price of an item as it compares to it's competitors and it should in no way automatically mean that the item is of poor quality... though there definitely seems to be that implication for many.
It may well be that SOMETIMES a "cheap" item is also of poor quality but that is NOT always the case... in fact sometimes an expensive item can be of poor quality... price does NOT necessarily equate to quality.
I have never owned or fired the NEA rifles but from what I've read there is absolutely NOTHING WRONG with the quality of their product. The CORE15 product is excellent quality product from what I've seen and we looked very closely at it during the SHOT show. Poor quality can come from all parts of the market and at all price ranges... every product needs to be judged on it's actual merits and not on it's price point.
I haven't owned any Norinco AR's but I do NOT put them down... in fact when it was first announced (years ago) that there was a Chinese AR-15 coming that was going to sell for $600 to $700 I was excited... because I knew that it would open the AR market to hundreds if not thousands of new AR buyers who could afford a $600 gun but who couldn't afford a $1,500 to $2,000 AR (which is where prices were back then). The Norinco AR's may have been the best thing to happen to our market... and our business. In fact they prove that a cheap price does NOT have to mean poor quality.
People make purchase decisions for many different reasons... price is always a factor but so is "name", quality, features, options, etc.. If all that mattered was price then everyone would be driving the same car and it would be the cheapest car in the marketplace. Last time I looked there were a lot of different cars being made, with infinite options, colours, designs and price ranges... the "cheap" ones may not be the same as the expensive ones, but that not mean that the "cheap" ones are poor in quality... firearms are no different.
Instead of "cheap" why not use the words "less expensive". Just because something costs less doesn't mean it's of poor quality... just because you buy the most expensive item doesn't mean you have purchased the best quality item either.
Just my thoughts
