you really check your pagerank on 6 different websites? the digpagerank itself has a list of datacenters whats the point :S?
Whichever is first in google results I have started using digixmas's bulk pr checker tool for instances when I need to check PR for multiple websites.
I use a plugin for firefox It displays the pagerank in the bottom right of the browser. I can't display the link, but a quick Google will find it. The Web Developer plugin is also pretty good, with loads of tools including validation.
