Here is a free PR3 - 7 directory. I have used before and can say it works as promised.
createbacklinks.org/directory.php PR3 I think pretty sure it is.
seo-package.com is a PR7 but it spiders off and links you to it's sister sites also with text links. I really like this one! Some of the sister sites are PR6, PR2 about 12 different ones.
Here is one more, somuch.com I am going to sign up to it here shortly but I have not tried it yet.
