I would avoid Razer mice, I got two Mamba Elites and both of their mouse wheels are broken/bugged (if you scroll in one direction it scrolls back and forth, or scrolls twice when you want to scroll once). My sister got a Deathadder Elite and its mouse wheel is completely broken.

I picked up an Anker vertical mouse for like $12 from a used PC parts store and it's been working just as well in my opinion, pretty comfortable and still has a working scroll wheel.

Of course you could also buy a drawing tablet and set it to mouse/relative mode and play with that, which I did for a while, but the lack of a scroll wheel stops you from playing some games.
