Best gaming keyboard and mouse for a $1000 build

Try the CM Storm Quickfire Rapid. You can often find them on sale for decent prices, sometimes around 60$. The CM Storm Recon is also a highly underrated mouse. I use it myself, with a Microsoft keyboard(nothing too fancy). The Recon costs like 30$ right now. The Rosewill RK-9000 is also a nice keyboard for the price. Here's some links:
