Absolutely!!
No comparison...a 150, if you have never used one, they are still ahead of todays vacuums in many ways...but one important one in particular, the automatic height adjustment has never been equalled yet, it is still amazing how perfectly it will adjust from one carpet to the next, and too the workmanship on a 150 is unexcelled,they put everything they had into it, and boy did they have a winner....second pick, a 63, or a Citation, I know convertibles are good and popular, but overall the 60 series is overall built a little better, but really, the most world changing machine, and to my mind the most historically significant machine is the Dial a Matic,it is the model for most modern machines today, its as good or nearly as good as most built today, and it was made nearly 50 years ago!
