I don't have any comment on that particular sim, but most newer sims these days
use linear motors, 6 to a base.  I'd be curious about how fast the rock n ride
can go, and whether it has a pneumatic 'squishy' feeling (which may be
advantageous, depending on the simulation).

Have you ridden in it?  And, of course, a bargain is a bargain!  Chances are if
you turn it down you'll occasionally wonder if you should have gotten it.  If
you do get it, you'll likely be able to resell it for the same price if you
don't like it.  And you can always throw more money at it for improvements, so
nearly anything can be changed...
