Mine's a Brother and is about 4 years old. My previous one, a Toyota, served me well for around 25 years, but one day it seized, and no amount of oiling and tlc enouraged it back to work.
My first machine was a Jones, which was straight stitch only. I can't imagine using a machine with only one stitch choice now! But, gosh, it was a workhorse, and that straight stitch was so neat. It meant, of course, that everything had to be either finished by hand or have French seams, but it didn't stop me churning out clothes for my children and myself - in those days home sewing was cheaper than shop bought, so that was a great motivator!
More recently I've bought an overlocker and an embroidery machine, both around 3 years old now.
