For confirmation of QLs on the Sabotuer armor, I can tell you 100% for certain that it drops up to QL300. You can find the super high QL stuff off of the 255 incarnator Heckler Bosses. Specifically the one that drops turn spirits (Syros?), they even share the drop slot.
I own a full QL300 suit on RK2, it's teh sexeh!
