The Bridgestone looks really clean. The others are mostly all decent choices depending on fit. I'd be less excited by the Performance bikes, but that's my vintage bias. I love my Motobecane, but I'm not sure I could enthusiastically encourage a relative newcomer to jump into the wonderful world of French parts when there are so many good alternatives.

Whenever you're shopping used, just be real careful to inspect the bike carefully, in good light. Focus especially on the front end. Lots of bikes show up for sale with bent forks/toptubes/downtubes. You've suffered enough. Make sure you don't buy someone else's trouble.
