I'm looking for a Stanley Clarke Short Scale bass, preferably the Brown Bass model, but I'm not pickey and will consider all options.  I'm also looking for the bass to be in mint condition.  I will definitley pay top dollar for the right bass.  

Have you checked the current '89 thread?  It's not a brown but...

There's one on ebay.
The guy who selling it lives not far from my home.
He says he's only shipping to Germany and Europe, but if you ask nicely...... I think it's a pretty looking bass.
