Paradigm Persona 3f and center channel

Curious to what the Persona 3f and the Persona Center have been selling for demo or used perfect condition. I see what the asking prices are but any insight to what they are actually going for would be appreciated. Asking because I have a chance to get both in the titanium color for 10k total from a dealer who is getting out. 
Could I play with these for a while and potentially make a few bucks? 

Thanks
