A requested update: so far, so good with the power steering. As I noted in my post from March, the Unisteer kit seems to help with the steering a fair amount. It has gotten consistently better with regard to smoothness, but still is not as consistently smooth as I feel it should be for nearly a grand. Perhaps part of my problem are my aggressive heavily treaded front tires. However, they are not markedly oversized from stock and to me really should not affect the smoothness of the assist except when stationary. My opinion still stands: a nice addition that really helps with low speed manuvering and positive steering with heavy front implements, but probably worth about $400, not $900.
