OK, no one makes a short shifter for the 6th gen accord aside from PSPEC. There are adapters, but they all pretty much suck in comparison. The PSPEC short shifter is $200 and it comes with the knob, boot, shifter, and all necessary hardware. Go to www.pspectuning.com for all the info. I have it and I can personally vouch for the quality of all the components of the kit. The picture in my sig is of the PSPEC short shifter. I have a few more if you want to see them.
I have a short shift adapter and I cut about 1in. off the size of the shift lever. Then just re thread it and install the factory/new shift knob. I think that's the best and most cost efficient thing to do. On a stock shifter lever, the throws are sooooo friggin long I used to hate it.
