UberSuggest?

[Neil797]

If you're looking for just a tool to find good keywords then lowfruits.io is worth checking out.  I've tried all the tools and I always find the keyword difficulty ratings are pretty poor (and the thing I value most!).  It doesn't do all the analysis that the other tools do but I'm finding it very accurate for finding easy keywords to rank for.  
You can get a couple of free reports to check it out I think.
