I had a Eureka Dial-A-Nap Upright Model 1425 (I think) which was bought in Florida in 1982. It cost in the range of $100 dollars which included a basic set of white plastic attachments. A basic classic Eureka white and dark blue upright with a plastic handle and a step on switch - no headlight. Nothing fancy, but it worked fantastically - even on deep plush carpet.
It lasted through several moves to new apartments, and was even owned by a friend for a few years. I replaced the outer bag and brush roll on the unit, but aside from that, it still runs great! Because I did not have room for it anymore, CountryGuy Gary up here in Ontario kindly agreed to adopt her from me in the last year - promising to take good care of her as she moved into old age! I'm sure Gary can tell you all if she is still doing her "thing"!!!
