SpyFu is a neat (and free) tool that can eliminate keywords that you may think are good to use, but may not convert well. It is a tool for Google Adwords and useful if you are trying to determine an estimated spend for individual keywords..
What I like is that they cover a wider demographic than the other paid tools available. Although the new WordTracker UK version is a great addition for our company, being that it is based in the UK, KeywordDiscovery seems to be a better choice for those in a European market. Major differences are the databases from which they pull their results. WordTracker uses 4 or 5 sources (e.g. MetaCrawler, DogPile and Overture), while KeywordDiscovery uses Google, Yahoo Groups, DMOZ, MSN, Teoma, Miva and over 50 other databases. They also pull from databases in Japan, the Netherlands, Australia, New Zealand, Sweden, Canada, Germany, France, Belgium, Switzerland, Denmark, Finland, Italy, Czech Republic, Russia, Spain, Mexico, Israel, South Africa, India, and Norway. In the UK alone they use 11 different engines including google.co.uk.

I use this keyword tool to see what terms companies are bidding on that are related to my query. Chances are, if they are bidding on it, then it's probably converting. This helps me eliminate broad terms as well (e.g. parts, cars). I guess you can use other tools to base KEI (keyword effectiveness index) on and do close to the same thing, but SpyFu makes it a little easier and faster.
It will also show you misspelled terms. Of course many of these tools have this function but again, this tool does it quicker. Here's an example of what SpyFu came up with when I searched for 'advanced auto parts';
advaced auto parts
advancd auto parts
advancded auto parts
advence auto parts
advenced auto parts
after market auto parts
aftermarket auto parts
anvance auto parts
So it doesn't just show ergonomic misspellings, it also shows 'stoopid' misspellings.
