Not sure on the PIA, but for report generators I've been extremely happy with DevExpress reporting.

I've also used Active Reports, but it's more expensive for the very same feature set. http://www.gcactivereports.com/
And Telerik has a reporting package, but it wasn't nearly as mature as the other two last time I looked (several years ago). http://www.telerik.com/products/reporting.aspx
All three should be able to export any report to Word, Excel, PDF, etc, without any third party dependance.
