I know this is not what you asked but I have found that if a tool helps your daily business (or even hobby) then it's worth paying for it.
I'm currently paying ~$600 / month only in tools and I don't regret a single penny of that amount
again, not what you asked for but I thought I'd share my view on the subject
I agree with you, in fact I too pay monthly fees and even have an acct at estibot, I'm currently writing an article/blog post showcasing free tools that domainers can use to help them find good domains.
Thanks for your help
