Dunlavy SC4 Speakers

I got a line on a set of Dunlavy SC4 speakers and wanted to know in very condition what is the used market value or what are they worth? I do not want to start a thread on what speaker is better than The Dunlavy's due to the fact that I can get the Dunlavy's dropped at my door with no shipping, But I still don't want to over pay for a used set of speakers becasue they have a cult like following that drives up the price. Also these are the original SC4's early run.

Thanks
