Buses to Zihuatanejo

Does anyone have any experience or advice on traveling from PV via primera bus to Zihuantanejo? I would appreciate you comments/advice.
Thanks

gosh I have been looking to see if anybody has answered you.. cause I would like to know too! How much is it? are there highway pirates? (maybe I watch to many movies) How long does it take to get there?
hopefully soon... hang in there..

I tried to get information on a ticket from Vallarta to Zihua last year and was told that there were no direct buses and I would have to take a bus to Guadalajara and then buy a ticket for Zihua from there.
