Spencer is offering his January 2001 Featured Custom over at the TalkBass site.  Current asking price is $4500, lowered from the original price since he posted it for sale at the end of June.  Oddly, I didn't find a previous thread on this, though I may have missed it.  
 
Ad thread is here and the FC page for this bass is here.

Almost exactly what I'm looking for in my next custom. But not for a few years yet ;-(
