Usher SW-520

Hello all!
I'm new here and am looking to expand my setup.  Anyone here know where I might be able to pick up a pair of Usher SW-520 bass modules?  

For those curious I have 4 S-520 and a S-525 as my center.  It's all powered by an Onkyo integrated. Im looking to ad a little to the front sound stage for both 5.1 listening and stereo when I break out the vinyl.  

Thanks for your time!

P.S. Sorry if this is in the wrong area looked around and found no better place to post this.
P.S.S.  I'm in Connecticut, are there any other Usher speaker owners in my area?

I don't know why my post was removed, it met all the guidelines.  I was simply posting that I think I might be selling my SW-520 (and S-520s) if this user was still looking.  Sorry if digging up an old post irked someone, but as another thread on agon mentions, these only come up for sale every 5-6 years and I happen to be thinking about selling mine so thought someone seeking them out might be interested.
This got me thinking ... If one has a paid ad running are they allowed to state that in the forums ? With restraint of course . Not a mass marketing type deal .
Why was the post deleted?  Is it because nothing can be sold on the forums without the site getting a cut? if not, why cant I contact Octalon? The site is 404ing the p.m. page!!!!
