eBay, Craigslist, the pawn shop, your backyard. And of course the forums (once you meet the criteria).

The Seiko & Citizen Watch Forum on http://www.thewatchsite.com/ could be worth a look; 50 post minimum to list a for sale ad. There's always Chronotrader if you're brave...
I actually very rarely see modern Grand Seiko's being offered for sale on the Seiko & Citizen Watch Forum.
Yep, WUS seems to have more GS owners (it even has its own sub-forum). SCWF is mostly made up of vintage Seiko collectors and fans.
