I have just run across this thread so I will post some things to answer some of the questions about the Landing Gear Box and Switch top.
The 925.00 price is for the all Metal Version, it is a bit over kill for hobbyist.
We make these for companies that provide simulators for the military both foreign and domestic.
You see when the simulator is not your own you tend to not be as careful and for that reason the Resin version is not recommended for commercial use.
Now the Landing Light switch top is made of resin in white and all but the jewels are painted silver.
The one pictured is the old type made from a replica, our new version is made from a mold of the real part, and the base is a small amount larger for mounting purposes.
The jewels do not light up in the real part; they are just plastic drops of resin.
Dead man is right the Gear Box is very complicated and is not USB but it is not needed to be.
The G press switch is set up through a board like the Xkeys matrix.
Then the light in the handle is connected to a Light output Board.
The Thumb button activates the solenoid to unlock the Gear Handle.
