A webpages PR can go up and down over time not only because of the PR of the backlinks but also the type of site that the backlink is comming from.
From what I have learned, Google takes several factors into consideration when passing on PR from one page to another such as relevance and quality of content. If this is correct then you may get a link from a page with PR of 5 but if it is not relevant to your page, it may only bennefit you as a PR 2 or so page.
I am not sure if this is 100% true but with Googles lattest changes I would not doubt it.
Never Give Up!!!
