As far as I know, input-remapper will handle any mouse, regardless of how many buttons it has, since they just show up as human interface devices.
I use, and really like, the razer naga v2 hyperspeed mmo mouse, but it’s about $100 USD. I’ve never tried them, but the Redragon mice are inexpensive and generally get good reviews.
All of them should work just fine with Linux, though any rgb bullshit might not be adjustable with anything that isn’t razer.
I downvoted it because it’s not funny. It’s real, valuable information. It’s not the kind of thing that belongs in c/nottheonion because there’s nothing odd or funny about it.
