Shaun, I have both, and I like them both, but I won't get rid of my original 9X. There's just something about it that's very comfortable. It has a bit of heft that the newer radios don't have, and I like it. Makes it feel like a substantial piece of kit, if that makes any sense. Kevin told me long ago that no matter how good the new 9XR Pro gets, I'll still find myself reaching for the good old 9X sometimes, and he was right. I've only been doing this for three years, but the 9X has a feel about it that makes anyone feel like an old pro.
I recently replaced a gimbal in my 9X and I'm getting a parts collection together for that TX so if you need anything give a holler and we'll see if we can't fix you up. I'm also keeping an eye out for old 9Xs at good prices to keep for parts.
