Is word tracker paid service still a beneficial one?

I feel word tracker had been one of the best tools when it comes to keyword research. We at Search Engine Genie had been using word tracker paid service for a very long time. But now there are lots of other tools to do free keyword research. Adwords sandbox, google suggest , yahoo search marketing keyword suggestion tool everything works pretty good and all of them are free.

The amount of keyword suggestions word tracker provides cannot be matched by the free service offered by them. I also think their paid keyword suggestion database is updated more often then their free database is. If you are going to use it for multiple accounts it will be a great time saver. but if your using it just for your own domain then you can get away with the free one no problem I personally recommend sticking with the free one unless you are SEO company who are looking for large scale keyword research for clients
