I was in the same boat as you, I stumbled upon adams and did my first polish by hand on my brand new truck and quickly realized I needed a DA Polisher if I really wanted to get it to look perfect. I bought the PC in April and it was great at correcting my wife's car, the only problem is the vibration gets to you after a while and you might even feel it the next morning.
I wanted to upgrade and was debating between the Cyclo and the Rupes Bigfoot 15, ultimately I decided on the Rupes 15 for a couple of reasons...... people say it has a little more correcting power than the Cyclo (I know my vehicles are in good shape, but I've done a few friends vehicles for $$$ and they had a lot of swirls from bad washing habits, so I wanted that ability), both machines have the same throw and I like that it has a narrower profile compared to the Cyclo.
I didn't get a chance to use it until last week......I did a full paint correction on my truck and the difference was night and day. The Rupes 15 has so much less vibration and it was really comfortable and enjoyable to use. Whatever you do I'd say don't bother getting a PC and put the money towards the Rupes or Cyclo.
