I just recieved my swarowski 80 atm with 20-60 eye piece. When doing my research prior to purchase the list was Kowa's new model was the top ,then Lieca ,then swaro, and ziess was somewhere next in line. Can't comment on the Ziess but the Swaro is awsome. Check out magnumgun outfitters in Loydminister Alberta. They had great pricing. They have an online site and I think they carry Ziess aswell
