Your best/only option is to find a used board and desolder the switches from it, it takes under an hour to desolder them all.
Some good options that are usually inexpensive:
Apple Extended Keyboard II - Dampened, tactile, non-clicky
Dell AT101W - Tactile, non-clicky blacks
There are plenty of clicky ALPS boards that pop up on ebay,
this one should have very good complicated clicky ALPS and since it has an ugly cord and cigarette burn, it should go for cheap and be a great donor board.
