I didn´t double check but did you miss Aaron Wall´s keyword tool?

The overture timeouts kill me though. If you start to get the php error message you might want to press stop in your browser otherwise your cpu load will get close to freezing. Good tool though. If I need just US data I use the digitalpoint tool.
I´m really eager for that seomoz sandbox tool to be released but it´s taking its time
