What are Screen Actor's Guild (SAG) rates for appearances?

I know that a Big Star can of course demand anything they darn well want, but I'm looking for "what am I as a venue required to pay any member of SAG who's coming to a convention or similar appearance"? That is, the minimum that I could pay someone and not get them and myself in trouble for violating the rules?


It seems their site is down and I have no idea where to go elsewhere to look.
