where is another good place to search for b&w's?

I am on here all the time, on craigslist and have a word in to local dealers for some used b&w's. i am looking for a good deal on some of their 800 series floor standing speakers. they are dam hard to come by. my top two choices are nautilus 802's or 803 d's.. any suggestions on other places to look?
thank you,
bill
