don’t forget "whatchamacallit"
Only problem is you still can’t tell what kind of traffic you can expect but you can see how many pages a search engine has about your key phrase. This can give you an estimate of what kind of traffic this keyword will get without traffic estimation tools.
Obviously a keypharse with 12,000 pages indexed by Google does not get the same amount of traffic a keyphrase with 260,000 pages indexed.
