I have a site www.petsfund.com where I raise funds each xmas season for a local no-kill animal shelter. I'm selling text links for $3.00 which will run until 9/27/07 when I begin the effort again. The site was PR3 until the recent update but you may still find it worthwhile to get a cheap long term link. Check it out, you'll get a link and do something for the animals.
