Yeah, I have a Lily58 and this appeals to me since I would actually like one more column. Mine was pre-made and has an encoder where I would like my "[" to be so this would also help solve a problem I'm not too well equipped to solve. And since I'm not really up to procuring the equipment and time to learn to solder I would love to buy one of these pre-made: anyone know where I can buy a pre-built version?
