I have a '86 Tempo and it is 22 lbs. and an awesome ride. Buy the Super Sport, you won't regret it.
BTW, I totally disagree about the World Sport not being worth more than $100.00. I had one and sold it for much more and it had a 4130 frame, 12 speed Suntour Accushift that was extremely smooth and precise, nice wheels. you cannot buy ANYTHING for around $100.00 new that would compare to that bike, nothing. The guy that bought it emailed me a week later thanking me for keeping it in such good shape and for cleaning it up so well.
To a flipper, maybe not worth it. To a rider, definitely worth it.
