in the end it depends on what you are looking for. keyclone is pretty simple to set up... technically, just run your wows and start keyclone. done. tweak your do-not-pass and that's about it. want keyclone to auto-start your wows? add that. want keyclone to layout your wows in a cool fashion. add that. simple.

if you want to deal with tweaking scripting code for each key you want to deal with, then hkn might be for you. just be careful (link )
