ACES II Motion Curing Seats

Does anyone know of any companies that provide reasonably priced (around +- $2,000) Motion Cueing Seats in an ACES II form factor?

I am aware of companies like Moog and Sterling but those seats are extremely expensive. I've also seen the GS-4 but its not an ACES II, nor does it provide belt restraint. The only other company I know is Gheko and it is not an ACES II variant either.

Thanks for all the help folks :)

P.S, I know some folks might be in the progress of building such a seat but the time to release said G-Seat is a very long ways away.
