whats the deal with the officially licensed wireless xbox controllers?...
how many 3rd party companies have an official license?
anyone recommend a 3rd party wireless controller?
do 3rd party wireless controllers damage your system?
have there ever been evidence of any wireless controller harming your system (goes for any 3rd party controller for any system)

tried to make the questions as "to-the-point" as possible...

any help on these questions would be greatly appreciated


EDIT: found this info on this site: http://www.epinions.com/content_1493016708

Be careful buying 3rd party controllers, and accessories for your console. Some of these are of good quality, but some are cheaply made. This doesn’t just mean that it may break easily, but it could damage your console. What happens is these don’t always draw the right amount of power from the system that it should. This could damage the controller ports on your console, making it necessary to have your system repaired.
...does this apply for the officially licensed controllers made for systems now?...could there be other reasons that 3rd party controllers would damage a console?
