Where to Sell Besides eBay?

For reason both personal and photographic, and with no critical judgement of the GRDII, I'm selling my whole outfit that I've barely used.

eBay is the obvious place to sell, but is there some forum that focuses on buying and selling cameras like the Ricoh and the Sigma...?

I know there are a couple of good ones for 4/3 cameras and for each of the major brands and wondered if there was some comparable one for the small art cameras.

Thanks.

Mark
