try to find a good butted steel frame in your size first. brands for around $200 popular among those here include fuji, motobecane, nishiki, miyata, univega and sekai. look for downtube shifters, aluminum rims and an on-frame rear derailleur hanger. braze-ons for racks, cage, shifters and rear brake cable are a plus.

worry about getting a peugeot later. here in seattle, there are a hundred peugeots for sale, but very few that have the characteristics i stated above. many might look cool, but they're over 30 lbs with heavy frames and steel rims. good luck.
