I have been using March scopes for 6+ years now. They are pricey, indestructible, highly reliable and have phenomenal optics.

My newest is a March-X 10-60X56 HM, and it sets the standard for optical glass.

They are difficult to get as March is a small Japanese company which hand assembles all their scopes and test the snot out of them before shipping.

What specs have you set out for a scope?
