I'm going to tread the water between John and Jim. The big advantage over the U-series was the 700C wheelset. That, in addition to the lugless construction saved a couple of pounds. It was Peugeot's base racing model, while the UO10 was an upper, sports/touring model.

The one area where I'm going to have to respectfully disagree with Jim is regarding the derailleur. They were not the top line SLJ but the standard offering SX410, according to my literature.

At $5.00 you got a super bargain.
