Hi Maxina, I wish I had a suggestion, I'm sorry that I don't.
Back in the day (years ago) I used a Belkin/Razer Nostromo 52 that was nice. It felt nice on the hand and had good response and key action. I never used it to its full capabilities but it certainly provided additional options.
I also remember trying a Razer Naga mouse, which has a slew of additional buttons on the side of the mouse but sadly I could never quite get the feel for using that many buttons with my thumb.
Out of those two, I recommend the Belkin/Razer game pad. But as I shared, this was many years ago so there may be new-and-improved options on the market nowadays.
