Adwords Keyword Tool is being loopy - anyone else?

[Vadym]

I was just about to start some keyword research.

I get into Adword Keyword Tool, and type in my keywords to get variations and see stats.

Insufficient Data for everything.

So I get curious, and type in "books".

Insufficient Data for everything.

Am I the only one getting the loopy results? This is quite annoying. What keyword tools do you use for research?

Thanks, Norb, I've read that, but how about paid?

Like.. well, I'm looking at this one right now.
