What do you use for keyword search and analysis? (I miss Niche-mania's tool for this!!)

[icrystal]

Once upon a time i was a niche-mania member and one of the things i LOVED was the tool for keyword analysis.

THen i had to stop my online business for a couple of years - obviously i'm back now - but i just tried to sign up again to use this great tool and... well... it's seems to be gone

So... what do you suggest i use instead? OR has Big Mike put this great tool somewhere else on the web?

Thanks!

PS Micro niche finder looks great but is there a tool you like that is free or perhaps a minimal monthly fee?
