i paid 60 for arctosa and 62 for naga hex and I ain't regretting it, gaming peripherals are a convinience if you use the machine for lots of hours for work etc. But they are pretty hard to get used to , so don't be discouraged (especially the naga hex, it took me like 2 weeks to get used to the surface feeling, not even counting the extra buttons and shit)
I used to have a microsoft wireless that came with my pc and I ended up with some serious tendonitis after a week full of projects for uni, so I rushed and change the shit
