Hi fellow Razer Fans! I decided to spend my earnings this month for a Razer keyboard. I want to buy a silent one, but not sure which one is the best for me.(Deathstalker Essential / Deathstalker Classic/ Deathstalker Ultimate, or something else) Please help, which one is better and which one has the less problem with it. I hope you can help me with some ideas. Thx Cheers!
