I have several, I've sewn all my life so machines very important. Right now 4 machines are used regularly. I've had machine problems while trying to complete a project by certain date. Sooo.. it's very convient to have at least 1 backup.
I sew PIece, small quilted pieces on my workhorse a Singer 778 that I purchased in 1976. have not regretted it.
I inherited my Mom's late 1950 Singer 301. which I quilt my larger quilts on.(It sat in my son's basement for several years till we could rescue it.) She purchased it second hand.
I purchased a Janome 3138 just to take to class as above machines weigh a ton. I really wanted a FW which was my next purchase on E-Bay. At the same time I bid on a Singer 66. Won both. FW & 3138 alternate going to class with me.
My DH has learned how to service vintage machines. so one of these days he will work on the 66 so I can use it to quilt large quilts and give Mom's machine a rest.
Last Fall I stopped at an estate sale, saW a filthy cabinet with a black machine in it. Very pretty cabinet & dirty macghine caME HOME WITH ME FOR JUST $20.00. That machine is a 27 treadle factory authorized electric conversion. Still need DH tinkering.
My prize machine in my mind is an 1830 White treadle That I purchased for $3.00 45 years ago. One day it will also get working.
I also inherited one of my grandmother's Reliable machine, don't know year or model, but she died over 60 yrs ago. Some day it will work also.
I have 4 Grand daughters who will each inherit one of my vintage machines, hopefully in working order.
