It another nice FREE tool to find keywords and of course domains.
It is similar to Google adsense tool.
It produced similar results as Google for keywords but not exactly the same.
When I tried a more specialized keyword, it produced different suggestions than Google.
The point being, they are not using Google’s database.
As you said the price is right.

They must be from Google because as hypocrites Google they also cansor innocent words like ANAL
Nice to have another alternative for researching long tail keywords – thanks for posting.
Nice tool. I test a couple of keywords and the results are no bad.
Its not bad, but I prefer Wordtrackers keyword tool http://freekeywords.wordtracker.com/. However, I do like the “related keywords” section.
