Which Power Rack&Pinion easiest/cheapest install?

Thanks for those links Blown71.

I already had gathered info about Ackerman geometry and such, but that CircleTrack-link puts it all nicely in one extensive article.
The custom Unisteer unit seems kinda steep in price for me, and I've also read some bad mojo about them on the net.

The lost turning radius is something to look into aswell.
Perhaps it's possible to create an extra eye in the steering arm, shorter to the lower balljoint to regain full turning radius again.
