In that AVS thread that was linked, there was a link to buy issues from Future directly. Cost me $15 to import the mag for the triggers, and then got them only to find one of the triggers wouldn't snap on. I had to super glue it to the controller.
For those who hate the PS3 triggers, these are great. I can now play Motorstorm w/o my hands getting tired, and use the control scheme for RS:V and CoD4 that has shoot and aim mapped to the triggers. I really found the configuration of Uncharted to be counter-intuitive, and hope that all games going forward give the option of using the triggers for firing.
