Electronical Music Instruments by Radio Shack

While browsing through old Radio Shack Catalogs (which we sometimes do, it is a strange hobby), we found two different Electronical Music Instruments. The first ’15 Note Electronic Organ kit’ is from 1976, the second ‘Realistic Synthesizer by Moog MG-1’ is from 1981. Do you recognise them? Which of those do you prefer to own?
