Has anyone had any good experiences with Paid Directory Submission, as in paying for your website to be placed in a directory?

Which websites have worked for you, and why?

The standard ones are;

BOTW – $149 – Domain rank 5.9, 9 million links in
Yahoo – $299 – No idea on the stats
What U Seek – $24 – Domain rank 5.5, 500K links in
Canny Link – $19 – Domain rank 4.6, 900K links in
ProLink – $19 – Domain Rank 5.1, 116K links in
Pegasus – $69 – Domain Rank 5.9, 172k links in
