Looking for partial private keys that I can play around with.

[cyptomania]

I'm looking for partial private keys but need some proof,a link to the original posting,forum etc.

I don't mean to be rude or anything to you guys but I can waste months of computer time running my program for some guy who want to screw me around,10 or more missing characters is fine,50/50 if I crack it but please if you can prove it's a real key.

There was a few I found right here on bitcointalk years ago but I can't seem to find them now,point me to the posts and the 50/50 is still good,thanks guys.
