Domain Stats - Bulk multithreading checks

Sometimes you need to check domain stats - availability, link popularity, presence in DMOZ, Yahoo, etc. It's hard to find a good web service that can lookup all the parameters fast.

I often use this handy software - Available Domains Pro
It's fast and easy-to-use. Supported: Yahoo, Alexa, Altavista, Overture, Google, AllTheWeb, DMOZ/Yahoo directory!

Google PR - resources

To check one site's google PR - http://www.checkpagerank.com/
It additionally checks if it's a "faked" PR (there is a method to link any domain with no PR at all to PR-rich web site, this tools can handle this).

Bulk Google PR Checker (the one I prefer) - http://www.smartpagerank.com/bulk-pagerank-checker.php
