Razer is good at asking a lot on money on crap that doesn´t hold up so dunno about that too.
The Nostromo N52 I got was a lot cheaper but as mentioned low quality also. The Logitech one is probably quite okay but the layout is not as good as the Fang Gameboard I feel.
I think the market is there but the advertizing is wrong so people don´t realize it´s that they are after instead of a regular keyboard... It´s a bit like 24p for cinema. It´s an awefully crappy standard but folks are so used to it some believe it´s actually good and that 50/60 hz material have an unnaturally good flow
I wouldn´t mind playing a bit extra for quality. My beloved Fang Gameboard was a bit to cheap I would preferr paying more for a more bullitproof design
