Wordtracker paid service -- which SE's do you query

To save time when using WT which engines and directories do you query

[Spyder_Cat]

Have been using Word Tracker for a while now (paid subscription).. was wondering which search engines or directories people here selected when finding out their keywords and phrases?

Does my question matter if results are based on estimation?

At the moment I just query google and msn results?

I would be interested to hear people strategies & thinkin g on this.
