Im using for mouse Corsair m65. I dont need a mouse mat for it. The mouse is great and the software that u get is easy and nice.
Corsair m65 costs 50$
U have also m40 its the same just has a optical sensor and hasnt the Sniper botton.
Corsair m40 costs 40$
I would recomend for keyboard the Corsair k70 but it costs 115$
That would ne 55$ over budget but i think its woorth it.
So i would get m40 and k70.
