The Rupes was my main polisher for 4 years but it died on me and the repair center told me that the issue is the electronic control unit and they are supposedly very expensive. Since I live in Canada it would already cost me an arm and a leg to send it to the USA for repair so with that added to the repair cost, it would very likelly come close to buying a new one. So I am done with Rupes.
The GG Boss 15 is now my main polisher. I don't like it as much as the Rupes 21 but it works. It stalls more than the Rupes even if the orbit is shorter, so I should have gotten the 21mm one instead since I do have to switch to my short throw polisher anytime there are curves on panel

That's unfortunate. Seems like a machine as well made (?) as that would back you up on a failure of any kind.
Just my observation. And, yeah...... I know I might hear that same old stuff that others have thrown at me. But, I'm just making my observations upon reading posts from others.
