Laurie's posts pretty much sum up the situation.  The upshot is there's little or no incentive now for vendors to make anything different or of a higher standard than the rest.  There are exceptions but you'll note their stuff is generally higher priced than most.

BTW, I'll revise my statement regarding "dozens" to "the majority".  You have to look at the whole of the market for the past eight or so years, though.  Comparing like for like across the standards of the day, the quality of bought stuff was generally high.  Maybe the scales have tipped in the other direction now but that's simply because of all the reasons stated above.  Sad, really.  The standards should have seen a steady increase, based on what we know about texture making and Poser's capabilities.  

The (fairly) recent rise in resource kits has, IMO, just about killed the texture market and is, IMO, the main reason why there are now lots of generic texture sets and prices are in the toilet.
