$45-60 Nagas on Amazon - no problem. Times change.
IMO, 20 bucks more certainly worth not having bullshit issues a couple of months in. Now, I am not saying Razer is the pinnacle of reliability, but it is certainly better than some noname vendor with shit reviews. The real question here is not what you get out of the box, but how it fares after some time and the difference shows.
Honestly, I believe Razer gets a bit of undeserved hate there, I use plenty of Razer stuff and the only one that gone to shit for me so far is their headset (and honestly I had Roccat headset too and damn, that one literally died horrible mechanical death 2 months in, so compared to that a year and a bit of Razer was amazing), the rest like keyboards, mouse, mic, mats are all solid couple years in for me.
