Great discussion; I too am debating between CX/CK20SE cab to replace a CS/NX. Like the CK20SE cab for what it has and can do, but fearful about how it will beat up lawns on loaded R14's. And like the CX but it doesn't do much more than a CS. I think I will go for the CX because it can do what I need it to do, instead of the CK of what it can do (but I don't need all of them).
