It takes all sorts of people to make this world. When i started my site i also got all kind of reciprocal link partners. I also got very good partners who gave me PR5 links in exchange for link at my PR0 link page.
I would suggest that while exchanging links you should look at the relevence of link than PR. Think of a situation if there were no search engines and you would exchange links for traffic.Then you will think in different terms and aim for quality and relevent links. That may be slow process and Then you will find more dependable link partners.And you will get traffic from these links also.
