Keyword Research Tool Problem

[Stevejobs2011]

Hi, I had been in SEO for around 2 to 3 years, I am looking for your suggestion if there is any best keyword research tool.

I tried almost most of the keyword research tool (both paid or free) but I found the following problem:

-Worktracker:  I think it is too difficult to use and understand as a non technical person.  I always wonder the data accuracy because when the same keyword appear in Google for few thousand traffic, it only appear in Wordtracker for few dozen or hundred of search.  Also I don't think they suggest any long trail keywords in my view.  The long trail keyword you can also find in free keyword search tool.

-Google Keywords Tool- Good, but it can only show 100 results.  I cannot get a better pictures of related or niches keywords.  I always find some competitive keywords can rank easily but some non competitive keywords usually very difficult to rank in some case.  It will depend on how you interpret the data results.

-Keyword Discovery and Wordstream-Although I really want to subscribe, but they are a way too expensive (you have to subscribe for 12 months).  I check with their free keywords tool but only shown very limited results.

Although there are some other like spyfu.com or keywords spy......

Is there any one can suggest me which is the best tool to start with keyword search for the long trail and niche keywords ?  or is there any way or trick to find the best keywords ?

Thank you.

I think the best one is Wordstream and i use it for a long time , as you said they are very expensive but they also have a month to month deal for $399 per month, try it one month and if you like it and will help you then sign for a year for 299 per month.

sorry i don't have any others to share, sure there is a many out there but this one (after i try many) work the best.
