FLEX PE14-2-150, and here's why...
It's smoother, quieter, and runs cooler (critical when buffing out large boats that take several hours). Little things, like its superb ergonomics, also make a huge difference when polishing a boat. The better the machine feels in your hand, the less fatigue you'll experience at the end of the day.
The PE14-2-150 also goes as low as 600 RPM (400 at the trigger), making it easier to control while buffing out small, intricate areas that don't require a higher speed.
