I believe mine was $795 (from Doug at SSG) 3 or so years ago. Don't know if they've gone up...
You are not insulting anybody by negotiating unless you are actually insulting. Don't be a prick, and even if they refuse, all will be well. After authenticating that it's the same exact model as other cheaper ones, I'd take the approach of telling them that you are not a low price shopper and would like to give them your business, but the price difference is too great in this case, and could they come down a bit. They say 'yes', or 'no'...
Just be prepared to buy if they do come down. Don't make them go through the effort and then pull back. That could get you marked as a douche no matter how nice you are. Be sure of your ability to buy (money and CLEO signature or Trust).
