Yes indeed! I'm a big fan of estate sales and such, but since I gave up garment construction I don't do buttonholes any more so I love the Japanese vintage machines that go up to zigzag and can sew anything. If you have an active Craig's List or Next Door you can often find some great deals.
I'm thinking of it as a specialty piece of equipment, just bring out the button-holer! I like having a back-up/travel machine anyway, early during Covid both my trusty old vintage and fancy modern Bernina went down and I was sewing on a bottom of the line Brother, but it made masks just fine.
Again with the Sparrows, many people are finding this to be a great machine to take to classes and such. Yes, plastic case but mechanical machine at a good price.
