Depends on teh frame, the fit and your intended use.

First, if it doesn't fit well, its not worth anything to you.

I wouldn't spend any money on a hi tensile steel frame. There were plenty back in the day. Check the model name, look for frame tube stickers and try to determine the frame material. Double butted Cr-Mo is best imo. Butted Magnanese alloys are next best but often came with hi-ten forks and stays as they were targeted at lower price points. I think bikes with plain steel forks and stays make fine beater beer bikes. But, I'm not going to restore one to pristine.
