Best keyword tool?

[fpamoh]

I know there have been many threads on the best keyword tool, and the general consensus is "Keyword Tracker".

However, I am after a tool that distinguishes between singular, and plural search terms (as the results in the search engines differ aswell) (Keyword Tracker does not do this)

For instance, I need a tool that will tell me how many searches were on the word "gardener", and on "gardeners" as opposed to bunching them together, to tell me there are £2.6 million searches.

Does anyone know if such tool is available?

Thanks in advance.

Wordtracker doesn't bunch the plural and singular variations together.

NicheBot is a cool free tool that uses Keyword Discovery and WordTracker results. You can also download a csv of your results.
