I don't think I will be investing in a set, no matter how cheap.

I cant speak for them on a jeep, but I fitted them to an RX Turbo and an Escort Mexico in years gone by and they did NOT make the ride harsher - in fact the consensus was they made the ride more compliant... (and yes, they did improve turn in and general axle control / high speed handling as you would expect).
Others at the club reported the same thing.
Our invented rationale was that they allowed the pins to rotate more easily, ie. without initially sticking, which gave a more progressive, smoother start to suspension movement in the direction the suspension is supposed to move while preventing twists etc. in directions you didn't want things to move.
They definately improved both the ride and cornering and were not "harsh" at all.
