(not my words)
"They call their 301 model a "low-cost" solution - and while I do agree that's quite affordable for professional/commercial simulators, I don't think many hardcore gamers will be ready to hand out $37,500 for it.
These models are designed for professional use - in fact, for added realism they can even offer you a more advanced model:
We also have a 401 with a base price of $52000.00 USD. The 401 has a 4th, yaw axis, which provides 180 degrees of rotation. This was designed to be used as a training simulator for professional race drivers and other high performance drivers."
