Short Throw Shifter

Has anyone installed the Short Throw Shifter from 3KGT Motorsports? How do you like it, and was the installation difficult? I am thinking of installing one on my 92 VR4.

Also, recommenditions for replacement shift knobs would be appreciated.

Thanks

Im getting one soon, but for a Magna (australian Diamante, they were manuals)

I'm interested to know how they go too.
