Subject: Italy Flexi Rail Pass

Hello I just joined this Travel Group. Im going to Italy in several weeks and was wondering if anyone purchased the Rail Pass rather than purchased tickets for each train trip. It seems the one Im interested in - the 4 days within 8 day pass, for $159, is higher than the total cost of several trip estimates Ive gotten from http://www.cit-tours.com/ptitaly.htm Any input is appreciated.
