I don't have power steering, I have no intention on fitting an electric pump, just more parasitic drag through the alternator and I imagine it would make the steering that much more 'numb'.
I removed the power steering to improve feedback from the car and it has worked to no end, can definitely feel changes in road surface and the limit of traction.
I am inclined to agree with agreeable slick, if you can live without power steering, remove the power steering.
