I was wondering what the good folks on The Gauge use for couplers. I am not sure if this is the appropriate area for this post, as I was going to do a photo comparison, only to find my camera needs recharging. I wanted to show the Kadee scale #58 coupler next to some of the other knuckle couplers on the market. My point being is that it is amazing the difference they make in photos {especially when lightly painted a rust/brown color}, almost making other knuckle couplers look "horn hookish". Hmm..hope I dont ruffle any feathers with this, it's just that they make THAT big of a difference. It is understandable that some with larger layouts may not prefer to switch over all at once considering the initial cost output, but rather those with smaller layouts, or just starting out might want to consider this as an option. One other thing, they seem to work just fine with the other knuckle couplers on the market. I am still amazed after purchasing a fine kit, the additition of the #58's make...it still wows me every time. Like I said, I wanted to do a photo comparison {and will}, but the camera wasnt up to it tonight. However, I am interested to see what others think about these couplers. {hehe...no, I do NOT work for Kadee]. Stuart.
