PPC Spy Tools, how many are there?

[blackhorse]

Of the current popular PPC Spy tools, this what I was able to come up with:

PPC Bully
Ispionage
Hexatrack
KeywordSpy
Google Cash Detective
SpyFu
KeyCompete
Undercover Profits
AdSpyPro

Can you guys help me add to this list. I'm sure there are others. Trying to find out the strengths/weaknesses of each.
