Looking for recommendations on a power polisher to speed up future detailing.

My three week old E430 Sport's first polish/wax will be done by hand, based on excellent product recommendations read from this thread.

I understand that rpm should be kept low (1K-3K) and tool constantly moving (in direction of airflow), so as not to remove paint. Buffing and polishing pads used of course should be of high quality.

Thanks.

James
