The stock shifter mod seems to be the way to go these days. It is extremely simple. Take out the shifter and move the plastic ball higher up on the shaft. A hammer and a vise should make quick work of it. I think there are notches on the shift lever that the ball will naturally rest in. I think people bring it one notch up.
Hell, if you wanted to be real ghetto you might be able to just bang on the top of your shift lever with a BFH and accomplish the same thing. You didn't get that idea from me though. Super ghetto.
