Well said, you couldn't give me a non-spektrum system because at some point your going to get Glitched.
You should consider what you need for options as well, I love my DX6 because it's simple, I only need 3 switches-normal/idle up, throttle hold and expo on/off. Heading hold on/off is never used anyways. I can't tell you how many times I have seen someone crash and burn because they hit the wrong switch. Im using my DX6 for 3D and it works fine, at some point I will upgrade to the DX7 but my DX6 does everthing I need it to do.
