A tenth of that gets you a basic but solid 88-key Roland FP-10; that's something they will sell a shit ton of and which shares components with several other pianos.

It's also worth noting that a piano or piano-like keyboard will be taking _much_ greater impacts than any typist inflicts on a computer keyboard; a music keyboard needs a mechanical action that can properly and rapidly reset the keys, withstanding many rapidly repeated simultaneous heavy strikes.
