About $350 for the actual top. There are some parts you need like a no drill header, tailgate bar and door surrounds, but these are the things you will need anyways to go from a hard top to soft top.
You will find that people who have this top love them. Im sure there are more than a few threads on here about these tops. If you do a quick search on the top right hand corner of the page you will find them all and other peoples reviews.
Heres pics on and off.
