Question : Best Registry Cleaning Program?

3 Registry Programs: [1] Max Registry Cleaner; [2] Registry Fix; [3] Registry Mechanic. I have numbers 2 and 3; and, am considering augmenting them with number 1. I would like comments/opinions/recommendations  on which is the best/safest cleaner. For example: Max Registry found 1,604 errors; the other 2, less than 100.
That difference scares me a little. The registry must be treated delicately.
Thanks!

Answer : Best Registry Cleaning Program?

Of those 3, Registry Mechanic is the one with well known credibility, I've used it before, now I used TuneUp Utilities.

Max Registry Cleaner <-- I don't know this one, but google results brought me to the freedownloadscenter site which is a BAD source.

Registry Fix<-- I don't know either.
If you want to choose between those 3 I'd pick Registry Mechanic for sure.
