couplers

[sgtcarl1]

I have a question for anyone: I am up-grading my rolling stock and will be replacing many of my hook/horn couplers with knuckle couplers. I would like to use Kaydee couplers, but they seem to be quite expensive. Any way, I have observed that are are several different models/styles of them. Which is the best? Are any other couplers as good as Kaydee? I really don't want to spend money for a" name," if there is something that is comparable. Also, any suggestions as to what to with the hook/horn units? I have several unopened packages of them. Any body want them, you can have them for the postage.
