Any thoughts about this spider quad carbon frame?

[Stet Hindes]

I'm just getting back into this after being disappointed with my last controller. I am buying a quad 550 setup and was considering this frame given I will be hanging a still camera from the unit. What do you guys think about this frame design, and any comments about the seller? I would be interested in similar setups, especially ones where I can fold the legs. For this one I can remove 4 bolts and fold the legs.

Thanks in advance
