Rescued a Sylvania Superset!

[TUD1]

Decided to go on a shopping spree today and buy stuff I don't need with money I don't have. Hit up 4 shops, and nothing. About ready to call it a day and go home, when I decided to go to one more shop that I rarely go to. At the very back, all sad and lonely, I spied a console TV marked $14.99. I felt so sorry for it, since I know nobody would have bought it. Turns out to be an April 1987 Sylvania Superset. I remember hearing the name Superset on here a few times, anybody have an opinion on these? I'm going to go pick it up tomorrow.
