What keyboard/mouse to get?

Today I was at my local electronics shop and I noticed some razer products on display. There was a keyboard and some mouse glued to a table. I tried clicking the keyboard and was instantly amazed. I can't remember its exact name, but it was called razer huntsman. It's switches reminded me of red switches but clicky. I also tried holding one of the mouse. It was called basilisk x hyperspeed and it felt really good. This leads me to my question, what keyboard or mouse should I get? I mainly play on red switches and I use claw grip for my mouse. Will that work on the Basilisk x hyperspeed? I already have a viper mini and quite enjoy it, but I want to also expand my mouse collection. I have a budget of 100 SGD but I don't mind spending a bit more if it is worth it.
