Had a chance today to directly compare Leupold Mk4s against the Tasco Super duper sniper(whatever). I have to say the Tasco was optically equal. Shorter, way lighter, same exact retical/subtension & of coarse, alot less money. Things I didn't like as much as Leupold: Clicks were not very audible/tactile. They were there, and the knobs turn with alot less effort, but forget counting clicks. Would have to use visual placement. The rear parallax adjustment sucks as bad as front parallax scopes, and is of coarse -a bitch to turn. Leupold side adjustment is superior. But for ~300bucks the Tasco impressed me.
