Magnum Mania!

Magnum is available on Starz' streaming service. Stars has a 7 day free trial or if you get Starz with a cable/satellite service you can get their streaming service for no additional cost. Unlike cozi they have all 8 seasons and its streaming/on demand. After the free trial (if you don't have cable) its $8.99/month.
Finally another streaming location since netflix does not have it Magnum streaming anymore.
