I decided to get a g400 because I'd like to try the optical(nonlazer) sensor

My old g500 has some aesthetic problems the fancy cord fabric is torn but the actual functional plastic mouse cord is still good, and the logo/paint has worn off a bit, but its still 100% functional.

I was wondering if anyone has an old/used maybe discarded for whatever reason, razer naga or logitech g600, that is still functional, I would love to trade for one, a friend of mine loves the naga but his recently broke.

I'm not sure how the mice compare, but from what I hear the naga has a pretty bad rep, so I'm hoping someone has one they bought but maybe wasn't completely happy with it for whatever reason? I know the sensor on those MMO mice aren't very good.
