Ahh so that brings the price point closer to the apex.
I think they are both about the same as far as what they can do, it also depends on what you want it to do and the modules you want to add on. I have my eye on several modules and they were all cheaper with the rke. As far as quality, I havent seen an apex in person so i can't give an opinion, but the rke is pretty sturdy and I am very happy with it. I program it on my netbook with a cable hooked to the unit so it's idiot proof, which is what I needed.
