I ordered a throttle mount and got it last week. I could not be happier. Using it with a wheelstand pro with the warthog centerstick mount.
I was thinking about ordering one for the stick to have a side mount aswell.
But as you stated yourself; that price is a bit high.
It's sturdy, easy to mount/detach, Extremely well made, very sleek nice design.
Its exactly what I was looking for.
The only thing you need to build is the plate which the stick/throttle is mounted on. Only two hex screws. Very simple.
