I am also looking into buying one of these and from what ive discovered online, yeah the regular force FX saber is not recommended for duelling, as it damages the LEDS.

However there is a comapny who modifies these sabers and sells them as 'ultra FX force sabers'. They apparently put brighter luxeon LED's in them which also allows you to duel without breaking them. Also the 'blade' is detachable from the hilt unlike the regular sabers.

check out the ebay auction:

if your wondering about which saber to get, there is a guy on youtube who reviews pretty much all of them and gives you an idea of which is best out of the bunch: http://www.youtube.com/user/mcich
