Hello!

I'm looking to buy a road bike before heading back to school in August, and via craigslist I've found a few that are in my price range (250 tops). First is this Fuji Allegro, Valite tubing, 56cm (I'm 5'10", so that should be okay, right?) which is listed for $250.

I can try to bring down the price since with a few searches I've found that it was an entry level Fuji, but is it worth looking into?
Second is a 1985 Peugeot, which I've found 2 of: http://sfbay.craigslist.org/sby/bik/3892002495.html

I sent an email out asking, and one of them has a carbolite 103 sticker, and weinnman brakes.

Are any of these bikes worth the price? I'm new to the world of road bikes and really really don't know much, so I'd appreciate any advice you all have!! Thank you =]

EDIT:
I've also found these:
