Ok, is the 7424 the variable speed the one that is 3.5 or 4.7 amps? Does it matter? I have heard that maximum speed is what is needed to get out the biggest scratches.

The one that Meguiars and Griots sells -- which is it, as far as amps?

Thanks,

Hi:
The Porter Cable 7424 is listed at 3.7 amps in their catalog. Variable speed is 2,500 to 6,000.
It is available at 877-551-8665 for $119.95.
Hope that helps.
