Buy something in the range of 1.5-2K on amazon. You'll get Outemu Blue/Brown in that range. Cosmic Byte/Redgear and some other brands available.
No one's giving away a Cherry MX for that price unless it's an old TVS gold.
Just ordered a KB from amazon so HP KB will be up for sale very soon though you will have to visit service center as sometimes couple of keys get stuck but if you hit those keys hard they work fine which I don't like. It was purchased in Jan so official warranty apply. Let me know if interested
