Another option if you want spare parts is to buy a used Cherry MX black POS keyboard on ebay, they can be had for $20 sometimes. Just swap the springs. Example:
http://www.ebay.com/itm/G80-11900LUMEU-0-Cherry-Model-MX-11900-USB-CYA-White-Keyboard-W-Touchpad-/271225181010?pt=PCA_Mice_Trackballs&hash=item3f2647d352Just make sure that it's actually MX Black or MX clear. Email the seller, ask them to pop a keycap with a butterknife and take a picture. If not just keep searching on ebay, a cheap board will turn up.
As suggested earlier, the springs only option would be better if you only want springs, and don't care about spare keycaps, switches, etc. Also, Leopold keyboards are plate mounted as far as I know, which makes them much more of a PITA to mod than a standard PCB mount. You would need to be handy with a sodomy iron, vs just using tiny screwdrivers to pop open the switch housing. Unless your time isn't worth much, or you really want to learn about keyboard modding by taking a hands on approach, it's better to just buy another board.
