Do you have a favorite gun web site that allows 'wanted ads' or saved searches?

I have several 480 Ruger pistols. Rossi Puma once made the Model 92 lever action in 480 Ruger 12-15 years ago. I have 'saved searches' at gunbroker.com, Guns America, going on two years now - no luck. Where else can I post wanted or saved searches? Do you have a favorite dealer that is good at finding stuff I can contact? I would pay $$ for a useful tip or help.
