i went with the steeda tri- ax, and i love it. way better then the sloppy stock shifter.
from what ive heard, the tri-ax, WMG, and pro 5.0 are all great quality and the most suggested. think they are all around the same price too. around 160bucks.
but like de_troit said , check craigslist. i know on CL new york, some guy has been selling 3 shifters for t-5's, 60 bucks a peice, he just doesnt know what kind they are apparently.
