STi Short Throw for the 5 speed

I'm going to be trading my Legacy in for a 2.5RS (I'm looking cautiously at the WRX, but most likely won't get one) after this winter is over. I was looking through the Build & Price part of Subaru's site and noticed the STi Short Throw Shifter available for the 5 speed trannie. Is this a good short throw shifter, or would I be better off having them order me a Kartboy shifter and having them install it for me?
