EGW also makes them. Their machining is top notch. I don't think there is any reason to think that if choosing from PTG, NSS, or EGW you would come out a loser. They all make very quality products. You have multiple good options to choose from, no need to keep digging. Just buy one and rest assured that the lug will not be what's holding you back.

I've never bought anything EABCO branded.
