DA would be a good choice (that is if you can stand it's vibration) if you don't plan to do much of heavy corrections. Even if you do want to, modern compounds/polishes and pads are now available that can make heavy corrections on a DA possible....though it'll take longer time than a rotary....
Tell you what, a machine 'feeling' gathering is in the pipeline. A few guys wanted to get the feel of the few available machines so that they could choose which one would be more suitable for them. Maybe you want to join the 'fun'.....hehehe...

Getting a swirl free or hologram free finish with a rotary is far more difficult than burning through the clear coat....
