The three that I know of in terms of short shift kits are Pure (if you can find it), Neuspeed, and DC Sports. All three work the same way. I have the DC Sports shifter kit, and it works fine. Some people say you get a "vague" shift feel after the install. But, if you get a short shift knob, the throws will feel a bit more sure. Keep in mind though, that it will not shorten the shifter itself all that much. It will shorten the throws. There was a short shift lever that was out a while back for the 4th and 5th gen Preludes (don't know the brand), but it has been out of production for some time.
You may want to consider shortening your stock shift lever as a do-it-yourself. This involves cutting the lever. If you are willing to do this, instructions can be found here:
