Brass to consumables ratio?

[sfc_mark]

...I'd like to order some 9mm and 223 pistol brass, but can't seem to find a really good deal on some once-fired. If anyone wants to offer a suggestion where I can buy in bulk (I'm thinking at least 500, preferably more like 1000-5000 or more) and save some dough, I'm willing to drop the money and consider it my initial investment. ...

You can get the .223 from River Valley Ordnance Works (http://www.rvow.com/server/index.php/brass) at $125/1000 cleaned, deprimed and full-length sized. Not sure where to buy 9mm right now. I usually just fill up my range bag when I go to the local indoor range.
