I have the Zeiss 4.5-14x44mm Conquest with the Z800 and can tell you the price at optics planet is much lower than what I paid about a year ago at two different places (from the gun maker and another from an eBay retailer).......based upon my search last year, this is a great price on a great scope.
Here are three sites that claim to beat optics planet by almost $100......never heard of these sites so who knows besides any warranty is with the Mfg. I paid $850 for mine, optics planet has it for $750 and these are in the $660 to 680 range.
Try SWFA, I buy all my scopes there. They have an area called the "sample list", it is where they sell all display and show scopes, they have good prices on them and are all factory refurbished and fully factory warrantied as new. I have bought at least 10 scopes in the last few years from them and never had a problem.
