The ones receiving damaged items are always the most vocal and then there are the bashers who enjoy just fanning the flames - they don't have the piece and have no interest in it, but they jump on the opportunity to be negative.
In reality there is probably a less than 1% of these arriving with issues. It frequently seems the same people always have problems with items - and they may be bad luck, bad delivery people or whatever. But just because one person receives an item twice, both with issues, doesn't mean the whole batch is a problem.
And I'd agree with Sideshow CS - forums can be the WORST place for actually getting an impression of an item. For all the posts of great pictures and people that love it there are 100 posts from people trying to bash it, sometimes for a reason, but frequently just so they can post crap (hi Bodie).
