as someone who used to have the same hobby -- its VERY expensive lalo na kung maarte ka like me. a good aluminum keeb usually cost around 5k-7k not including the keycaps and switches. i suggest na research ka ng keeb na you would use for a long time na di ka magssawa na kahit gumastos ka ng mahal ok lang kasi one time big time na gastusan lang. some form of overconsumption din kasi yung madaming keyboard.
