Deleted Domain Name Search

Right now I am searching on whois.net's deleted domain search to see if i can find a good domain name that was previously registered. Whois.net has been the only search like this that I can find and I was wondering if any of you know of others. Also, is there a website or program that allows you to do a more specific search like saying a certain amount of characters or something???
