Hello everyone!

I'm looking into purchasing a bike to fix up. I really like peugeots. My only problem is I can't find a bike my size - 53cm. I'm not really sure where to begin. I can't afford to spend more than $200 straight up. I'm keeping an eye on all surrounding areas craiglists' with no luck. I figure, since its such a specific thing, I should ask for help from people who know what they're talking about (yes, that's you). A friend of mine has an old Peugeot (not sure of the model) but I am pretty sure it's from the 70's. Something like that would be nice. If I haven't mentioned already, a roadbike, not a mountainbike.

Any help would be appreciated.
Thanks,
Matthew
