Thanks for all the suggestions!
I ended up getting the LifThor, and it worked well for me.
I like the sturdy metal bracket to enclose the controller. I like that the arms are good for a thick tablet, I was able to use my fold even with the case with the pen sticking out the back. It is a bit heavy. It came in a nice box, and they even threw in a hat. Normally, when I get a free hat with something, I think that maybe I paid to much, but the Skyfire was close to the same price, so maybe not.
