I've already had a custom keyset printed by WASD, and they're great—if you are OK with thin ABS and OEM profile. They're very well made, but I wish for some other options, especially in a non-sculpted profile. If only somebody was custom printing DSA sets…
I've noticed that Signature Plastics do some limited custom dye-sub printing, as per their website. If you buy a print-to-order DSA or G20 set, you can order additional keys with it, as long as they have "standard legends", meaning something that SP already uses in a set. And yet, for example… They don't seem to offer media keys (pause/play, next track, prev track, mute, vol up, vol dn) anywhere, in any set, in any profile. So, I assume those are non-standard. It's a bit frustrating because I can buy those keys from Unicomp for my IBM keyboards with no problem! Why not from SP?
