I was looking for a new bike just to have on the side, I found a couple this is one.

He sends me this message about what exactly everything is, "It was a 1980s Nishiki 10 speed that I cleaned up a few years ago and gave it a basic paint job. It's a good frame that is Reynolds 531 steel and did not have any rust."
and he'll take 100 for it.

these three for 75, he says he has the wheels cranks and everything with them but they're off right now.

I was just wondering if any of these bikes would be worth getting?
They're very close and cheap I wouldn't mind spending the money if they were worth it.
I am just not very sure on if they're good bikes or worth the money.

I appreciate your replies ahead of time.
