Redcow - dont get too obsessive about the PR - although some would have you believe it's the end-all to how you rank in the SEs - it really means nothing nowadays. It hasnt been updated in some time, and there is even some that think it's purposely being shown incorrectly to throw off those people that are trying to optimize for Google.
If someone bases a trade request with you on PR, or they offer to sell you a link with a certain PR - I would advise you to run the other way
