Yeah, I've seen the same pattern with knives. If you just want a decent kitchen knife, you'll find tons of people who are absolutely certain, that it's physically impossible to cut anything unless the blade has been sharpened by a Japanese virgin under moonlight.

I assume, the value for money curve is a sigmoidal, where at a certain, relatively low price you get almost all the value and afterwards it only gets more expensive, but not better. But you never know, when you've reached the plateau.
