Here are some extremely good options if you want a gaming keyboard for a good price. I have experience with these as I have bought them with parts for computers I build for people.

Extremely good build quality. If a “customer” requests a keyboard then I usually get one of these unless he/she wants a specific keyboard. Only one color of back light (red) but it looks subtle and somewhat “intimidating” (if you will). Nice texture on the keys and rest.

I have had one of these for a while now. Colors of back light are red, blue, and mixtures of those two colors (pinks and purples). Good build quality, touchscreen media buttons for volume control. Shortcut buttons that are somewhat useless for gaming and I don’t use them much. Texture on keys is nice but gets dirty easily. Rest is REALLY nice and can be removed if needed.

Very similar to the one above in features. Many would say it is better simply because of the brand (that is all it is… the brand, don’t let anyone tell you other wise). Same color settings as the one above except it doesn’t “snap” to the color but has a wheel that can gradually change it. Whereas the one above has touch buttons that change the color to one of a hand full of preset colors. Good build quality like the rest of them. Nice soft texture very similar to the one above. Rest is kind of awkward in my opinion.
