Below is what I'm pondering posting to my local (DC) craigslist, and I'm wondering whether my $600 price is appropriate -- I'm trying to keep it low-ish to account for my not wanting to package and ship them:
     This is a full 6.0 surround set-up, as shown at      
http://tinyurl.com/bbwf4 -- I'm keeping my  
     subwoofers but selling all of the other speakers,  
     which are all 6 years old in very good condition:
          * Two nOrh black marble 4.0s for the main 
             front left/right speakers (see               
http://www.norh.com/products/norh4,  
             currently $700/pr)              
          * One nOrh prism 4.1 front center speaker  
             (see 
http://www.norh.com/products/prism,  
             currently $275/ea)
          * Three nOrh Pyramid speakers for rear  
             surround (see               
http://www.norh.com/products/pyramid,  
             currently $250/ea) (I have a 6.1 surround  
             receiver; if you have 5.1 you'll have 1 extra,  
             if you have 7.1 you need 1 more)
     As nOrh claims on their website, all of these  
     can play very very loud and sound great.
     The total price of $600 for all of them is  
     non-negotiable, payable in cash, and the  
     speakers must be picked up from Rockville MD.   
     I do not have the original shipping boxes.
Suggestions, please?
