I thought about one very briefly. Then, I looked at my HD500X and remembered how much I hated it. I never use amp sims, and the chorus just did nothing for me. The delays were nice, until I A/B'd them against the G-System or any TC delays for that matter. I did really like the size though.
If the Helix had Scenes, I might have given it a try, but I'm very glad Fractal came out with the FX8.
In one of the videos, they try to show how strong the chassis, but if you look closely, when the guy is stepping on the handle you can see the LCD flexing.
I'd try a used one when the price goes down though.......:mrgreen
