I use the site
www.searchtempest.com for CL ads. It also lists eBay and Amazon at the bottom. The search engine lets you put in a location, max driving distance, etc.
I had to sign up for Facebook at work when our GM assembly plant was shut down for COVID a couple of years ago. That was our plant leadership's communication method during the down time. Facebook Marketplace is like CL but on Facebook. Problem is you can't attach the links (I can't, might be operator error).
Have fun shopping! Looks like a couple of those grinders a close to you and a pretty good deal.
