Need honest opinion on TT choices...New vs used?

Are there manufactures that use better interior components? All the sinks, electronics, speakers etc....all seem to be ****. Now I realize that simple math says that they make these things with the thought that they are used 10-15 times a year. But are there any that use better components?

And I would imagine that all manufacturers have a bottom end, mid and high end....what are they and how can one tell the difference? I suppose price tells the bigger picture.
