http://www.link-vault.com/ - static links (in English), with a limit number of links, links up on one domain - about 5, the network grows, a lot of the Polish sites. You can choose to three titles at once for a single link and display the percentage spread. currently most effective system!
http://www.linkujpro.pl/ - Polish system of static links!
http://www.linkuj.pl/ - allows you to quickly stand out in the first place, the best for "older" sites because the number of pages zaindexowanych receive points that can be immediately used for the promotion of a page. You can not add pages without www (http://cos.pl) - can be added manually after sending an e-mail, you can not add pages to a directory (http://www.cos.pl/katalog/ ...) - acc. This is me some problems.
