Being specially a modeller and a Poser shader developer, I pull my hat for the GOOD texturers.
Nothing to say about if the price shoud be the same, less or more, but agreeding with some of the previous posters here, in ex, Sarsa make the most recognizable, surprising and astonishing  textures for the super quality and detail... and IMO those fairly worth the price she decides to ask.
Same with some others as Marforno, Danie, AerySoul, Tipol, Nursoda, Fenrissa, VirtualWorld, Sams3D, etc... Textures is not the same than Shaders... and if shaders can consume time and effort, textures pick much more, again, IMO.
I have seen wonderfull textures for my hairs and clothings... and I know very well how hard could be to "learn" each new 3d model for making the best for it... SOME are in that level, others, simply, try to.
But my 2 cents here are for the texturers: truly TRULY artists. The price matter is a personal decission and I respect that.

Don't tell me that I am wrong if I say I saw pointed ears this morning, in my mirror... they are there.
