First machine of my very own was given to me by my DH's parents in 1958 and it IS a Challenge by Sears. I say IS because it is the machine I use by choice to this day. I also have a Touch 'n Sew by Singer that we picked up at a yard sale for $5 along with an antique Queen Anne desk to put her on (also for $5) and have recently acquired a 1900 Arlington treadle (paid a little more than $5 - lol) that I just finished piecing a king quilt on. Also have an old Singer in a bentwood case and a New Home (knee driven) in a cabinet that belonged to my MIL. Don't care for either of those. The Challenge is the one I sew on 99% of the time.
