It's one of the first electronic machines singer made, so it's probably not really retro either. It was very modern then, and is still better that many machines made in the 80's and 90's.
I ain't mad atcha, just saying . . . it's not widely sought after by vintage collectors right now . . . . so now is the time to buy one if ya want it. In 20 years, it'll be like bakelite!
