Re: Arias.. Any experts?
In general the stuff labeled "Aria Pro II" (note the "II") is the cool coke, starting around 1980, some from 1978. That is around the same time that other Japanese manufacturers (Greco, Burny, Tokai) straightened up and made better quality things than the Americans did in the years prior to that.
But in 1977 pretty much everything is trash, including the same Japanese makers that later shine for quality.
