Alright...so you asked for Aftermarket, and that's what I'm going to put in front of you. The other guys did an awesome job reviewing the factory/stock options!
I went down the path of B&M QuickSilver ratchet shifter. Love it!!! Now keep in mind that's my only experience with aftermarket shifters, so there are probably plenty of other nice and better shifters, but for me this was about putting something in the car that did not look "race car" like and had as little of an impact as possible.
Keep in mind I did this while my coupe was completely stripped down, so plenty of room to do anything I wanted. Carpet was out, I did drill a slightly oversized hole in the floor, after taking the photo I did actually go back to put an one of these rubber rings over the openning to prevent the shift cable from getting cut. I am also running a line-lock, so there is the wiring going to the T-handle.
So here we go, tried to put these in somewhat of an order from START to FINISH.

These next two show you the reverse layout of the shifting cable and the throttle kcikdown cable. The RED cable is the gear selection cable. The steel line anchored to the trans case is the kickdown cable.
