I have a bunch of different websites like http://www.seekshopping.com and the best link exchange web site I came across was Spocka.com (http://www.spocka.com).

It's built on the osCommerce platform and they allow you to pound their server and get link exchanges quickly. For example, I can go to the view all links page and request a link with every member of the site with the push of one button. That's awesome!

So, Spocka.com is my recommendation as part of a link exchange campaign.
