I bought a 6.5-20 Zeiss Conquest Demo from Doug a couple years back. When I got it I couldn't tell a diff from new (other than the seal being broken). I would buy another Demo without hesitation.
Doug posts a bunch on these boards (not this one I don't recollect) but if he gets demo's that are scratched, missing something like box, papers, case, covers, or not up to "new" standards. He posts what he has for a super discount & they are gone in minutes. If it's not LNIB; it's not on the Demo list to buy.
I have also bought some new scopes from him. I wish everyone ran a business like him. A1!!!!!
