Steve, I see people wrestling with this dilema and worse, from time to time. It is a shame that we don't have a sort of industry standard for couplers, but there is a simple solution. Get over your aversion to KD"s and use them as YOUR standard. They really are not that bad, and they look beter than the Bachmann coupler, and you will find a KD conversion kit for just about anything! I supose if you have a lot of stock this could be a daunting task or may be just not practical, but for any one just starting out, this is a simple solution. I have seen people use interface cars with a different coupler on each end, for me that would be unacceptable. I will watch with interest to see how this gets resolved.
