You could try modular keyboard. mas tipid in the long run kasi hotswap lng ang keys compatible kahit sa Cherry MX keys.
You could try the cheapest in the market:
pwede din bare-bone lng din bilhin mo tpos ikaw nlng mag mabili ng gusto mong Keys.. pwede mix switch kung trip mo.. or mag order ka ding cutom na mga keycaps. pwedeng pwede..
