After reading this forum, I started checking out the 997 short shift kit and found it listed with an internet special price of $305 at Carlsen Porsche (link below).
Part number is 997-424-983-00, but they specifically list it as 2005+ 911, whereas they list greater vehicle compatibility for some of the other shift kit parts. Based on this thread, it sounds like it'll fit my '03 S, so I think I'm pick one up at this price.
Anyone ever order anything from them?
