Does anyone know of a website or software I can use that will tell me which of my web pages have the highest PR?

I have a website with over 1,000 web pages and I'd love to be able to know how many PR5 pages I have vs. PR 4 pages. And which ones they are.

As an example, I'd love to be able to enter my URL and have the website/SW spit back results like this:

www.pinnaclesys.com = PR7
www.pinnaclesys.com/pvt = PR6
www.pinnaclesys.com/dazzle = PR5
Etc. for all 1,000 of my web pages (or at least the top 100)

Hoping someone has a suggestion :)
