At the time it came out - that was bike was a good deal. It IS a lugged frame, and I bet the main tubes were butted. However, it did use cheaper stamped dropouts and came with pretty crappy components.
I have the next Centurion bike "up the line" -and it's in good condition, and let my brother ride it on Sundays. But as others have mentioned, there's no use jacking around with that bike unless it was just for the challenge.
No doubt though, the frame would provide a soft and comfortable "tour ride".........
