@ Sarvanshu : good question actually .. maybe everyone uses different page ranking algorithms.. am not sure... I am also not sure why no one has replied to this post ..
@sarvanshu - the most reliable source is the google toolbar. Different sites use different scripts to retrieve PR, and not all of them are reliable. (Google blocks any site that makes too many requests in a short time, so those sites will give you a PR of 0)
Also, different google servers can have different PR for the same blog, specially during a PR update.
This is an interesting topic. I'd also like to know more on this.
@Renie - Any clue why different servers of google itself hav different PR? Don't they all run on same algorithm?
