Welcome to Geekhack!
Although some people like the Razer, a lot of people have had many issues with them. From that perspective almost any keyboard will be a step up.
The thing is that there are so many to choose from. One approach is to decide what size keyboard (full size, TKL, 60%, 40%, or something between), what layout (probably US ANSI for you, which makes things considerably easier), what switches, LEDs or not, and then see what's available in that combination.
And also to go to a keyboard meeting up you can, as it's a great opportunity to try lots of different keyboards as well as meet many enthusiasts
