Cybernet is interesting, not only do they have a cool name but some of their products seem pretty nice. I've never seen one up close but they are still in business and they did contract manufacturing years ago along with having their own line of equipment. This is the only personal cassette player I've seen, there might be more. I love the late 70's mini-systems, the Kraus MiniPack on 1001hifi.com is made by Cybernet. http://www.1001hifi.com/amplifiers-1981-1990.html
