If it is a normal "blued" one (rather shiny and of very good quality) do not hesitate over 700$.
If it's a "matte" black slide, walk away. Or give half of the asked price. I wouldn't even buy this latter (chances that it is a refused production for the South Americas). To be honest, I can't proof it ... but know.
