seems like this question pops up every few months... probably ok though since my thoughts have changed over the past year on this topic. I bought an RKE when they first came out and it has worked ok for me for the past couple of years. If I could go back in time I would have waited for the Apex. From what I have seen from friends and read on the forums, Apex seems to be a more user friendly system and easily configure "out of the box" . I would switch if given the chance.
