Best tool for checking pr

What is the best tool according to you to check PR.I am actually using the oy oy toolbar for firefox to check pr...
Any other alternatives?

 

there is one over DP. check it out http://tools.digitalpoint.com/pagerank.php

 

I usually use this one website to find out the PR of a site:

http://www.prchecker.info/check_page_rank.php

It comes up on top if you do a google search for a page rank checker. I guess there are more up-to date accurate methods but this one does the trick for me.
