Which vintage Craig's list speaker pair would you buy and why?

No brainer.  Go with the bronze 

Craigs list has junk and people that rip you off.Why would you use it??

ebm - Actually I have had better luck on Craigslist than on this site. Although there are some people on Craigslist that are dishonest and some stuff is junk, that is the case anywhere and you can filter that out quickly by talking to the person. At least on Craigslist the stuff is local and you can see it and here it.  Unlike this site where I don't know how many times I have received misrepresented equipment through the years.

Done fine off Craigslist but it was in town so I could see and hear the pieces before making an offer. Picked up my Pass Labs amp and Aerial Acoustics speakers that way. Sold a pair of Apogee speakers on there as well. Lately I’ve done well with Facebook Market and actually find there’s better equipment there and you can find out a little about the seller before contacting them.
