I used to borrow my Mum's sewing machines, until she had a really crap modern Singer, when I finally bought my own (Elna 3003), probably about 30 years ago. It's still going strong and comes out for difficult or thick fabrics, but I bought my new Pfaff a couple of years ago cos the Elna's buttonholes were rubbish.
I've had two coverstitchers, one overlocker, and two embroidery machines. So not many.
I'm not counting my grandma's, then mum's, old Singer 28k (or is it a 128k, can't remember), or the other old ones bought as "decorative items".
