There are some very good alterations. If presented 500 cards, 100 of which were doctored by someone decent at it, I am positive I would not correctly identify a good number of them.
PSA has commercialized an appeal to authority - they are selling little but their (extremely dubious) authority. If you are going to do that, you need to be able to correctly judge what you are selling your authority on. Even worse, PSA is not just getting tricked by the best of carefully done alterations - they let tons get by that a 2 second glance can quickly tell a viewer is altered.
They generally are able to identify fakes in most issues, with some slip-ups. By and large there are few issues with convincing fakes extant.
