If she would prefer a road bike, I got a Motobecane Mirage Sport for about $400. It is on the low end for road bikes, but so far I have been very happy with mine. I too am short and on a budget!! I am 5'0" and the 51 cm fits me just fine. I got mine at a LBS, but it is also available through ebay for about $100 less. I just thought buying it through the LBS was a smart move for me since this particular shop gives free service for life.
