Try traderonline.com  I've found them there quite often (of course you see more westies than syncro westies).  The prices are stagering.  Most the westies I've seen are at least 8,000 and the few westie syncros I've seen are 15-20,000+  so like Peter said you'd be lucky to find one for 10,000 - or unlucky depending on how you look at it (blown engine, trashed drive train, trashed interior ect.)
