Any good niche keyword tools out there?

I am trying to do some keyword research. I have used Google Keyword tool and it is great - it just seems to take me a long time to get to some keywords that I think are worth using.

I have seen other keyword tools and some of them seem great (at least that is what the sales pages says) for speeding up the process of finding profitable keywords and long tail keywords.

I want to know if anyone has actually used some of these tools and do they actually do what they say they do. Are they worth the investment? Would they be understandable and useful for a newbie like me?

Please let me know as I could stand to speed up this keyword research stuff and know that I got it as right as possible.

Thanks for that data. I will check that out.
I thought I would get more answers from folks as I have seen
a LOT of keyword tools advertised - but I am not sure of there effectiveness.
Maybe that are not used that much and people just use Google Keyword tool.
