W55 $200 http://www.bestbuy.com/site/olspage.jsp? or W80 $250 http://www.bestbuy.com/site/olspage.jsp?
If i am going to choose between the two, I will prefer buying W80. Although W55 is cheaper i still prefer W80, having its feature: capable of face detection and steady shot image stabilization, which W55 do not offer.
