At some point (when I can find a kit) I'm gonna build a 96key board. I figure in the mean time I can get a numbpad kit to practice and to have a numbpad in the mean time. I see 3 kits, Satan Pad off Alieexpress which looks good but doesn't seem to be programmable, The Felix from unikeyboard which is programmable but kinda ugly and pricy. Also got a bluetooth one up ob mass drop but it doesn't seem programmable and is pricy. Any other options around? Should I just go for a premade one and if I really wanna mess with it I could de solder and re solder switches to it?
