hibar posted:KD offers "E" style couplers in their O gauge 740 series now. Sergent does not offer any O Scale couplers.
Yep, just was an example of a company that despite Kadee offering mass market scale head E style couplers went ahead and offered a more accurate coupler in HO, even some 1/64th couplers as well. Never hurts to have options, Kadee's are great use them now on most of my stuff, and yes the 700 series is my preference.
