What puller are you using on the crank damper?

I have a few pre-'09 engines i need to diassemble. I need to know what damper puller you guys are using...

I have used the one from O-Reilly's loaner program... no dice.
Then I bought one on Amazon that was guarateed to work... that didn't do it. I tried to modify the arms to give it more clearance around the damper sides... still no good.

My friend has a professionsl one he bought from the matco guy. I'm going to try that maybe tonite...

Pix would be great.
