please help!!!! dvorak

to all altkeyboard members, I've been searching for an electronic typewriter with the dvorak option. meaning not a  conversion but one that is built into the system as an option. from reading the threads and finding what little info to go by, I have come across two sources but not sure about it, first is the smith corona 250 and the second is the silver reed ez50. now, I am aware the ibm selectric can be converted into a dvorak but i'm not going that route, too many mech. parts to maintain. sorry. anyone with knowledge with what i'm questioning about please help. thanks again
