Just wondering...where else do people go to look for secondhand watches? Both dealers and forums?

Over the years, I think I've become a sleeping member on most watch forums. It was the scam sale on Watchuseek that reminded me years ago I had previously placed an advert over there but being 99% US, I hardly ever visit. I think I've also bought from eBay once before but I would be really hesitant these days for fear if scams and almost exclusively use this forum.
