Recommended Bid Management Software?

[videoninja]

Would anyone have recommendations for bid-management software/keyword tracking? Preferably a self-hosted solution and of course compatible with adwords and direct track.

Is Google Analytics maybe the best?

Bid management - Google Analytics ?!?!

Why not just use DirectTrack Bid Management. It can get expensive, but I've heard good things about it.
