Has anyone experience with stabilizing filters for FCP?

If so, which one is the best for stabilizing shaking images?

Thanks in advance

Have you tried the image stabilizer that comes with FCP? I used it once to help with a brief jolt in some footage and it helped. It's in the Video folder under the effects tab of the browser.

Have you tried iStablize?

Anyone mind explaining how to use the FCP Stabilize filter? I can't make heads or tails of it (and the manual doesn't really explain).

I've tried the iStabilize demo (brilliant program!) but I just can't commit the $$ at the moment.
