I have two copies of the 18-55lens right now and will be returning one of them.  people mentioned make sure you get a good copy that iS sharp.  How do I test this?  I'm new to this and just want to make sure I keep the better copy.

Over the years I owned 4 copies of that lens. They all

  • had heavy distortion @18mm
  • soft corners throughout the focal range wide open
  • were critically soft @55mm, no matter how much I stopped them down
  • had different sweet spots/ranges
  • some amount of decentering
  • flared like hell at certain settings
  • want to be stopped down to f5.6/f8 to get the most outa them
  • sucked up dust like nothing else I've owned before
