HELP! What polisher should I chose…?

Hey guys! I’m looking at getting my first polisher. I’m looking at these: (prices are all in CDN)

Griots g9 is $200 (used) Rupes LHR15ES is $400 (used) Milwaukee M18 15mm WIRELESS $440 (new, after tax)

I could probably haggle the used ones down a bit. The first two are wired and I currently have 2 Milwaukee batteries if I go with the new wireless one.

Now, I’m on a tight budget, but as I see all over the forum, people rave about the Rupes, as well as having a wireless setup with the Milwaukee.

Is it worth the extra $200+ to Invest in the Rupes or Milwaukee, or will the Griots be sufficient? I probably won’t have too many polishing jobs as i only detail in the warmer months and am from a smaller town.

Thanks guys! 😁
