Need help on keyword research

Like to know which keyword research tool that is easy and good to use it to find a keyword list with high search with low competition so that i can use the keyword list to build a cloaked site?

Currently i have serpattack pro and brad callen niche finder that i just buy it last 2 days and like to know which one is good to keep because i still can request for refund?

I saw some keyword research tool that is monthly subscription like IMeye, SEO Cockpit, Niche Shark and Niche Reaper and it look very easy to find many good keywords but their price is way expensive. Anyone know about this tool and is that any alternative?

Thanks

I have niche finder, it's barely an ok tool. If you don't use proxies with it, you will get locked out of google and will have to visit google manually over and over to solve the captchas to get it to work. That said, i've never used serp attack. I rely on market samurai for all of my information and it has yet to let me down..

I vote market samurai.. Check out their training videos and you'll be sold.

Google's key word tool works fine for getting key words for your site.The searched key words are getting stored by the Google.Most of the people use Google for their search.So, getting mostly used key words become easier by using the Google.Don't choose a key word with heavy traffic.Its better to choose a key word with less traffic so that it will be easier for you to get ranking.
