I know that Kadee is considered the industry standard for scale couplers. I have also noticed that Proto-Craft has some rather beautiful looking couplers on their website. My question is besides, Kadees, what other options are out there for scale couplers in O scale?
One of the things I don't like about the Kadees is their looseness or sloppiness. The Proto-Craft look nice but I have never used them before and was wondering how they work. Any other suggestions?
