Dave I would not waste your time swopping links with other low pr sites all it will do is take up your time, on the same footing a high pr ranking site is unlikely going to want to ad your link to there and give away link juice with no benifit to them.
High Pr blogs are good if they are do follow links, which some do not offer, I know on one of mine I get spam after spam comments that I filter, I add the comment and remove the link as it helps give me content and has no benifit to the person trying to waste my time, if it is a good post I would allow a link back.
For those reading this going and spamming high pr blogs is also old hat.
Make your site worthwhile and you will do well on google, pay to have your links in the right places will get you results.
Out of interest how much is ben charging you per month for SEO ?
